Mine is done 78 LTD II it has a slight positive .5 with no shims I'll live with that because I can stop fast and in a strait line when I put the 390 in 'll adjust the spring height so that I will have a little adjustment but if I had it to do again I WOULD! It's great to STOP.

Got a couple of pics for you.

Here you can see the angle difference between spindles if you look at the machined flat surface where dustshield bolts to.Front spindle is from my ´64 and the one at the back is from ´77 Mark V.

Here is spindles from ´78-´79 Ranchero on left and ´77 Mark V on right.You can see they are the same.My friend forgot to bring the caliber bracket so we didn´t have the chance to compare whats the difference between intermediate 10.5" disc and Fullsize 11.8" caliber brackets.If the calibers are the same,brackets should be different,right?

In looking in a Mitchell crash book it shows the 74 to 79 Thunderbird, 77 to 79 LTD II and Ranchero,74 to 79 Cougar,74 to 76 Mark IV,77 to 79 Mark V,75 to 76 Montego,75 to 76 Torino and Ranchero,75 to 78 Full size Mercury and Ford. all take the same spindle, #D4AZ-3105-6A I think the 5-6 is for left or right. All of the above take the same part# for upper and lower control arms, D7AZ-3082A upper and D7AZ-3078-9A, lower, all above take same rotor shield. The caliper brackets and rotors show different #s,as do the calipers. Did find different spindle #s for 73 to 76 full size Lincoln and 73 Thunderbird. I'm not sure how accurate these crash books are. Guess the spindles are all the same and you just need to match caliper mounting bracket to the rotor size and pick which caliper you need. Calipers must come with different bore sizes to make up differences in vehicle weight and or clamping force. Read an article that showed how to put full size Ford calipers on a F-150 or Bronco and all you needed was a brake hose from a Dodge. Said the Full size Ford caliper had almost the same piston area as the F-250 with 4 piston calipers. Looks like a lot of interchange possibilitys. I'm going to try the Bronco swap on my 78 and drug home the front end off of a 72 T-bird for my 67 Galaxie, just waiting for warmer weather.

The crash books are close to the hollander info I posted, with minor differences. I think rattpac may have hit the problem but he hasn't been back yet. And we lost TommiFins pictures?

I'aaaammmmmm Back!

Went Camping over the weekend.

I will take some photo's and see if I can show you where the difference lies.

Lets take another poll on this and ask how many have had sucess on the swap and if they could add from which donor Ford they borrowed the parts from. Also were they able to aline perfectly? by machine?

If a problem really exists with the spindles a fix can be made but may require some minor machining and an insert to obtain the correct camber.

Also let's see if Tommy can reload the photos and one other curious point on the mitchel guide 'does it show the eariler han 73 spindles to be the same?" remember somewhere 73-74 Ford went with their "Universal" bearing size and that would show a difference between 73 and eariler on part number but not necessarily axis change.

I dont know why the pics wont show anymore but just click on the link and you can go to my pics page.
i´ll try to measure the angle difference today.

Galaxie_406

Saw Tommies photos and spindle look pretty much the same sitting on a bench. However I mounted them in a bench jig and measured a slight spindle degree difference. I have a frame with the front end still on the car and I think I will mount the original spindle take some calcs then put on a disc brake spindle and take some more calcs. Will report on this later.

TommiFIN

I measured the angles today and i also found 3 deg difference.

Galaxie_406

Yep 2 1/2 to 3 degrees difference per my posting. I have also checked them on a 62 front suspension that I have sitting here. Good news have photos and will be uploading them shortly.

Galaxie_406

Back to puzzle. OK here's what I came up with, look at the photos this should clarify the swap. The old crusty spindle is a 1962 Ford/Merc spindle off of the car you will see in the proceeding photos. The clean black spindle is off a mid 70's Ford with the big bearings 74+ cannot remember exactly which car but I have 3 sets of mis 70's spindle and they are all the same.

First measurement is in the my home made holder (not very percise but will do) of the machined top of the old spindle showing approx 10 degrees and the spindle at 87.5 degrees. This tells me that the axis is 10 degrees but the spindle is not 90 degrees to axis.

Second measurement is of the newer type spindle showing the axis at 10 degrees and spindle at 90 degrees so the newer spindle is 90 degrees to axis.


Third measurement is of old spindle on car it was equipped on so suspension has not been tampered with. This showed old spindle to be 90 degrees when mounted.

Forth measurement is of new spindle showing that it is not 90 degrees but 2 1/2 degrees different! Showing is 92 1/2 degrees giving you Positive camber of 2 1/2 degrees and causing the top of the wheel to tilt outwards. This however should be able to be compensated by removing the shims on the upper control arm (Photo Attached)

Do you guys need any measurements from a clean spindle I took off a 78 Mercury Cougar before it gets installed. Let me know somehow.

ya it would be appreciated. all measurements will help . thanks chad

OK it's trig time. To date we know a few things,
1. the top to bottom of the ball joints attachment points are the same for the original and the disc donor 8-3/4"
2. As per Rattpac and Tommi with their time in checking degrees of difference between the two spindles we get 3 degrees appox. using the disc spindle.

If I still remember my trig a change of 3* using the 8-3/4" lenght would mean removeing 0.46" of shims to get back to the same camber as he had with the other spindle. My gut feeling is the top A-arm is a half inch long to use the disc spindle and still have the ability to add shims for both camber and caster adjustment. IMHO accurate spindle to ball joint angles are needed to confirm my thoughts. All comments welcome on my thinking.

Thanks Wayne for some educated calculations. Call me slow but what does IMHO mean?
