I'm getting ready to attach my subframe to my 1975 and I have a couple questions. First, is the crossmember the only other thing I need to attach at the same time, or are there other things I should make sure to attach before installing? Second, I'm looking in my service manual and it says in addition to the crossmember there is a "retainer and insulator", what are these items? Am I missing something or do I just bold on the cross member. Finally, does anyone have some pics so I can visualize what the attached crossmember looks like prior to installing. Thanks for any help!

Apologies that I can't find any 'under car' images with just the subframe in place (yet).

Y'all two keep each other out of trouble up there, okay?

I personally would clean and coat the subframe and front suspension pieces w/ POR-15- it can be brushed on and dries w/ a gloss finish. It's also alot tougher than regular paint and will still look good after driving the car. The subframe is heavy- alot of DIY'ers assemble it, put wheels and tires on it, and roll it over to their shell to bolt on.
