Thinking about what is next up for my 1975 F250 highboy and I am contemplating swapping out the body/radiator core mounts.
Any suggestions/recommendations to accomplish this.
More importantly does anyone have the appropriate tool made up to pull the old mounts off?
Thanks in advance

The rad core support mount bolts thread in from above. I did not understand this originally and cut them off at the frame w/ a sawzall. It was a huge pain in the rear, but possible through the front wheel well.
The body mounts were a bit more straightforward.
You need access to the front cab/firewall area. Remove the cover and get a socket on the head of the bolt. I used an impact gun on the bolt from below to break it loose. I had to soak w/ some penetrating oil and heat w/ a torch mult times to get it to move, they were so seized from time.
The rear cab ones are a bit easier. Remove the rubber plug, and break them loose from above. I then crawled under the truck and hit the bottom with a smaller bolt to pop them up out into the cab.
The nut/washer portion holding the bottom of the bushing is a bit harder to remove. The rubber is usually smashed enough to prevent you from pulling the sleeve out easily.
I made a puller by getting a 6" length of steel pipe that will just fit over the mount. Then get some all thread and thread it into the nut. Get a thick piece of flat steel and drill a hole in the middle, fitting it over the all thread. Finally put a nut/washer on the other side of the plate and start to tighten it all down. This will act as a puller to pull the mount on from the bottom. I was a huge pain getting this all done, but possible. I jacked up one side/corner at a time to make sure there wasn't too much movement between my body and frame.

I watched some YouTube videos, measured mine, have a 6" long piece of schedule 4 steel pipe that is just big enough to clear the lower bushing / washer (it's about /near 3-1/4" ID, is left over from a old C-band satellite dish yard mount pole), some threaded rod, nuts, and a die just to clean the exposed threads of body bolts, and a 1/4" thick piece of steel with hole all laying in a box with my unused poly bushing kit for the day I might, but haven't yet needed to. Thought I did, but turned out shimming the stock right rear cab mount about 3/16" between the top washer surface and lower cab floor surface cured the 45 year old slight lean and got my dents aligned just about perfectly. I also placed a screw type hose clamp on each upper half rubber to act as a "girdle" for supporting the rubber. I only loosened the bolts from above a few turns, then a block of wood on a jack, slid my 3" OD shim in place.

 

Here is the set up some one on here made to pull the body mounts apart. I hope they chime in and explain.

And if your body mount hardware is beyond salvage, Vintage 4x4 is making us replacements. I didnt buy this part from them, but I did get the transfer case brace mount, it was very nicely made.

I used a piece of an exhaust tip and made this puller.

Even though it is pricey, I would also get the kit from the link above. I got the lower retainers from LMC, but had to re-use the uppers. It looks like the kit above has everything.
