Guys I need to find out how any of ya'll mounted your aftermarket tranny cooler. I've looked at Mike's article on 73-87.com but since his radiator support is totally different I can't mount it the same. I have my AC condenser(?) still mounted in there before the radiator but thinking about taking that out. I'm trying to find a permanent way to fix this so no zipties through anything. I'm going to mount using metal strips or straps but I can't find anything good enough to tie to. I'm lost on this I've got the holes for the steel lines but that's it. I've been looking and still can't see anything that would work and be strong enough.
