exchanger sizes

[bigboremike]

Hi everyone~
i was wondering what size (1.8 1.7 2.0) heat exchangers will fit with which heads and also with which mufflers will fit with which setup--probably confusing the way i asked this but im mixed up too.

All of the exchangers just bolt up to the heads. The 73-74 2.0l's match to a different muffler than the 1.7-1.8's. The 75-76 2.0l's use a different set up entirely. The ideal set up is the 73-74 2.0l SSI exchangers and a 2.0l muffler.
