I'm almost curious enough to have the local autozone to order a set of those bushings for me, just to see if they fit because they look so similar. I'm still doing the legwork to see what takes a 2" cube bushing similar to the radiator mount.
I tried flipping a radiator mount once, even with liquid wrench, and pulled the darned thing out of its socket...



I have access to an early 90s GM to do testing with the older aluminum dog bones, if needed. They look to be of similar length and width. I'm in the progress of retrofitting some aluminum venture van mounts, and I'm not sure if those dog bones would play nice with these radiator mounts, may make the engine sit too far forward, these already bring it forward almost an inch.

 

I did some looking. I found square mount apparently found on the buick centry. I bet the bushing inside of it would fit the radiator mount perfectly...

if not, you could always stack these inside...

update:


I found a thread on w-body.com that states 3.7103 will fit torque struts (dog bone) but will apparently require drilling to fit...

Interesting. So the big question, when do you order some new goodies lol.

 

Soon!
I'll probably just order a set of those prothane or energy suspension dogbone bushings. I haven't found another radiator bushing yet. The venture van mounts I got have like new bushings in them, so I'm not in a huge hurry for them.

 

One more question before I pull the trigger. In the event I would have to drill it out, Would it be appropriate to use a bronze bushing instead of steel, if I have to drill it out ?

 

My concern with bronze would be that it might be too soft of a metal. I'm sure you could try it out and see what happens.
