Many years ago my Dad and I were replacing the C-4 in my old 71 coupe, and no matter what we did, we couldn't seem to get the convertor bolts to line up and fit into the flex plate. We tried three or four times, pull the tranny out, measure it up...try again. Still no luck...so we pull it again and then look it over, everything seems okay (it should all fit, it is all the same items that came out originally for the rebuild). So we decide to break for lunch. After awhile we come out and try again and it slips right in with no trouble this time...so we bolt bellhousing in and then it's time to tackle the flexplate bolts...only to realize we left out the convertor
(I still for the life of me cannot figure out how we could be so absent minded and not realize the convertor was not in there!).
Of course my other favorite was when I replaced the points one time...couldn't figure out why the car wouldn't fire up...it would just crank and crank with no fire....then I saw the rotor sitting on the other fender
....makes you feel really stupid sometimes!!
My buddy had to one up me though, he rebuilt his engine and got it installed and ready to fire up...but couldn't get any oil pressure at all....til we found out he never installed his oil pump drive shaft!
Same friend was also very eager to drive his Camaro right fresh out of the paintshop...still didn't have any outside door handles (but the latches were there), bumpers or anything...including the hood latch...he felt the bailing wire he found would hold...until he hit about 60 miles an hour...and then the hood flew up, slammed into the windshield...messed up the hood, broke the winshield, and dented the roof a little...not to mention messing up a $2500 paint job!
Ahhhh the good ol' days!!
I could probably write a book with all the stupidity I've seen...and done in my youth (and currently too!)
