Front Alignment Shim Nuts

[Clark D.]

I have a 1966 Coupe Small Block. I would like to find out if the nuts on the front alignment shim bolts had lock washers behind them or not. On Vettes I have looked at I have seen it both ways, with and without. Which is correct? Yes, I have an AIM, however the drawing is pretty fuzzy although it looks as though there were no lock washers. Thanks in advance.

Clark,

I posted the same question myself recently, and the consensus was that on '66 a lock washer and "tall" nut were used, which is what I found on my '66.

Clark, I agree with the lock washers- it is the 67 that use the self locking
nuts without washers. Most suppliers send you the self locking nuts when you
order for 66. Robert

Remember the originals are fine thread items also, not the coarse thread used with the self locking bolts.

An interesting "tidbit": 1963 to sometime in 1966 used fine thread upper a-arm shaft retaining bolts with plain nuts and lockwashers. Sometime in 1966 through 1967 used fine thread bolts with a stover-type, self-locking nut. 1968-82 used coarse thread bolts with a stover-type, self-locking nut.
