I got mine through JEGS (Hooker).They didn't list them in the book but I got the part # and ordered them through them.They were supposed to fit a F body but didn't clear the booster,that was easly taken care of.I really think that they are universal for cars,you just need to know that you will have to modify them a little bit,what the heck,we're taking slant sixes and we are modifying them way beyond what they were designed for anyways.I haven't gotten anything that I didn't have to cut up or twist to make work.Most of the stuff isn't really cheap for a slant,if you want that, build a small block chevy.I LOVE MY HOOKERS. Was able to install a EVAC system and put on duals.Best thing I did was use the REMFLEX gaskets.No leaks.Like they say watch E-Bag or even try Craigs list.
i just checked and there they are!
