I have a set of heat exchangers from a 1972 1.7 going to waste and am tired of the kludgy 1976 2.0 set I have with my 1976 2.0

I understand that if I score ssi heat exchangers it is probably a moot point and I saw the lovely photos on the Bowlsby site, but I cannot seem to find an answer about stock ID. I can take the ones I have off and directly compare, but if I could know in advance I could collect the J tubes etc.

So - anyone know the pipe IDs for 1.7 vs stock 2.0?

Thanks - this would help a lot. My budget just was massively reduced when a tree fell on my wife's car (parked). Here in the midwest the air will kill you. And I worried about quakes in California.

Anyone know? I did use the search engine.

I believe you can use the 1.7's you just need the hanger for the 1.7.

Don't know either what muff you are using so that might matter as well.

This was the quickest reference I could find:

Measuring the O.D, I get 35mm for the 1.7 and 40mm for the 2.0. Cold not get an accurate ID due to the weld at the flange.
