Ok... what have i got

[Interceptor]

Started the swap to 88 small block Chevy engine.
My frame has adjustable mounts of some sort. I was told they were for LS1. Not sure.
Look at photo of current trees in my frame, do you recognize make?

If I knew what aftermarket frame mounts I may be able to order the top part so an older 350 mount will bolt up. If not I can fabricate to make work

Looks a lot like the Novak kit I ran in my YJ when I V8 swapped it.

They actually look just like the one's you need: https://www.novak-adapt.com/catalog/engine-mounts/mmx-wc1/

You just need the block plates and the isolators.

I sold you that frame. Those mounts came from Novak and at the time labeled as HEMI mounts on their site.

Looking at their site now I don't see HEMI called out however looking at the "Universal" MOPAR mounts it looks very similar. I'd call them and tell them what you have and I'd bet they could get you the right parts to work with the Chevy.

Thanks for everyone's input. I have ordered parts from Novak to simplify installation. Next hurdle is placement front to rear
