[TR] TR4A IRS Rear Trailing Arm Issue

[Jerry Van Vlack]

Hi Jim, I just looked at a spare TA and the hole looks to be 3/4 inch. It's 
a cast in hole not drilled. Also if you decide to replace the TA keep in 
mind the 4A TA's are different than the TR6 ones. I don't know if the 250 
TA's are like the 4A or the 6's. The difference is in the bump stops 
positions. TR6 are on the TA's and 4A's are on the body.
Trust this helps. Marv Gruber might have a good replacement. I've CC him on 
this email.

List:
I decided to take a break on my TR6 engine bay reinstall and work on the 67
TR4A IRS.  After dissembling the drivers side rear suspension, I noticed the
hole in the rear of the arm for the shock link is wallowed out.  What's the
correct diameter of the hole?  I don't have a spare trailing arm to check
and any ideas on creative solution to fix it?



Thanks,
