Trailing arm shims
Hi
I'm installing trailing arms to my 68 after rebuild.
I have the slotted shims from Paragon and is about to drill the hole in 4o'clock position as seen in another post regards using these slotted types shims on older vettes.
However, the ones that I have are too long to fit in the frame pocket.
Do I have the wrong shims, or can someone chime in on whats wrong here?
No way that these shimns can be tugged into the frame.
Thoughts are well appreciated.

Hi n,
Length of shim?
My 71 originals are 4 1/2" long with a 1 1/2" slot. They slip into place on the t-arm bolt, and drop into the pocket easily.
Has any work been done on the control arm pocket?
Regards,
Alan

My shims are of the same dimensions.
Shims are Paragons 3618K. For year 62-82
The frame has been repaired with Paragon replacements kick-up reinforcement and new #3 cross frame.
The trailing arm bolt hole is aligned per AIM frame specs.
So are you saying that the opening in the frame pocket is maybe too high at the bottom end.
I have no specification of the opening, other than the replacement parts.
That parts was corroded away on my frame.

Hi Alan
I'm afraid that I do have some extra steel at the bottom of the hole!
With the TA hanging freely in the pocket by the bolt, and can go as low as the shock absorber when fully extended.
I would expect the trailing arm should be able to lower at last for the full length of the shocks travel?
However, lookinh at the length of the shim, I can't see how a cottor pin can fix it with the exsisting dimension.
The location of the TA bolt hole has not changed lengthwise, but adjusted up/down as the bottom of the frame towards the new crossmember has been repaired.

Unfortunately the dimensions of the frame pocket give you no place to secure the slotted shims. You need the shims with two holes (much less convenient) so they do not come loose.
