I ran at the track this weekend and this was the first time I used my nitrous kit (100hp shot). Unfortunately, it resulted in bent spring perches on my 8" rearend. I'll defintely need to replace these, but all I can find is perches for 3" diameter axles. My 8" has the smaller diameter tubing where the U-bolts engage.

Does anyone know of a source for spring perches which will fit this smaller diameter (sorry, I haven't had a chance to measure the actual diameter yet)? Or will I be forced to possibly build some or buy a used rearend housing to swap everything into?

You are referring to the plates and not the actual perches on the rear end housing right?
What I did before I upgraded to my 9 inch perches was weld a plate on the bottom of the perch and re-drill the holes... it added strength to the wimpy factory plates.

The perches I see from companies like Moroso have the entire assembly which has the rounded cut-out so it can be welded directly to the 3" axle housing. I can't use these because mine is smaller than 3".

Are you saying that just the plate (i.e. the portion which rides on the leaf spring) can be cut off and replaced? If so, that might be a possibility. I'll have to look to see if the vertical portion of this mount is still intact.

I did the same thing to my car years ago. I ended up welding some flat plate to the bottom off the perch then milling it off at the original perch angle. The plate ends up being a wedge shape filling in the bent portion of the perch. Then I reinforced things by welding steel plates from the housing tubes to the rear of the perches.

Thanks for all the feedback. My son-in-law is a welder, so I'll see if he can help me replace and reinforce the mounting surface of the perches.
