rear shock tower repair info needed

[dascoupeguy]

I'm sure some coupe owners have had this issue... busted rear shock tower due to metal fatigue... the previous owner had attempted a crude repair that included sandwiching the existing metal between upper and lower 'repair rings'. To my amazement it appears that these rings are not welded to the existing metal.

I'm going to have proper replacement plates (rings) welded in place.

Does anyone know what the OEM diameter of the hole is(where the rubber bushing is pressed through)? There is no metal left for which to measure. Also no rust! Yay!

Thanks!

You can go to this site for sheet metal. Tom as dismantled several coupes and has quite a stock sheet metal for sale.

Here are some photos of what I did. The hole is 1" diameter. I would not use any old coupe tower parts for this repair. They are likely to already be fatigued. I have seen some entire replacement cup pieces - just not sure where.

Sven... thanks for the pics... I know what needed to be done, just needed some measurements.
