Differences in SSI models
 

Hi guys, I have an '83 SC that I am in search of gently used SSIs for. I know for an '83 I would typically use the "thick flange" model.

I noticed SSI makes thick flange exchangers for the '80-'83 3.0 and, under a separate model number, for the '84-'89 3.2. The flange thickness on both models is apparently the same.

My question is are these parts interchangeable? Can I use the 3.2 exchangers on my '83 3.0?

Thanks in advance!

I thought I'd read that the pipe diameter is larger for the 3.2 SSI's. THen i also thought that I had read Dansk was no longer making both models.

The insert into the heads would be larger on the carrera boxes.
The C2 boxes are thick flange but no inserts.
