Hi all, So I have this very strange conundrum with my truck and I want to know if I'm going crazy.

Some months back I had my frame straightened because sometime in it's past before I got the truck it had been wrecked on the pass side and someone backwoods straightened the frame (I could see the chain indents on the frame...). Anyway after the straightening the shop attempted to do an alignment however they broke one of the camber bolts in the process, I thought no big deal I'll just get all new ones because 30 year old bolts and what not...well now after months and about 12 different brands/sources I'm still no closer to figuring this out. Every one I order says they should fit however they all arrive as 4" bolts, but the ones I took off were 5.1", so if I try to use the ones that "fit" they are way too short and no threads come though the nut... I've even tried to locate ones that are 5.1" long however have no luck searching for such a thing...

So I'm wondering has any one else run into this issue? or is there something seriously wrong with my truck? Because seems to me the only way someone in the past would have been able to change such a bolt would be to cut the control arm mounts off the frame and re-weld wider ones that use a control arm that still looks correct (doesn't seem likely)

TLDR What is the stock length of the front camber bolts on a 1991 D150 RWD Club Cab Long Bed.

 

can you post pics of the control arms and mounts? sounds like someone has messed with something. i have never had an issue with the upper control arm bolts. it is likely someone has bent things or did something they shouldn't have

 

Unfortunately my truck is packed away for the winter so I cannot get better pictures than these.

I did extensive research and was able to maybe find the source of the woes, according to one of the mopar parts websites which has the diagram of the control arm, the 1990-1991 trucks utilize a different part number for the cam bolt kits (as ref no. 1) than the 1992-1993 (ref no. 2). However they are all listed under fitting 1990-1993 trucks (the years for the diagram), the cam bolts are also not separately listed as replicable parts numbers for the 1990-1991 trucks, only 1992-1993 (as shown by ref no. 3 which are cam bolts only). The only way this is recognizable is if you read the descriptions, otherwise the part numbers are listed as fitting 1990-1993.

I see on your profile you have a 1993, perhaps this is why they worked on your truck? I do have the original bolts and they measure to 5" and found one listing for NOS on the part number 3621931 and they look identical to the ones removed from my truck. Do you have a measurement on either your original bolts or the replacements you've used?
