Welcome to the home of doing the right thing the wrong way.
I had some new shocks laying around for an '88 Dodge D150, and my Tahoe still had the original shocks at 295k miles. I looked up the specs and they were pretty close, so I decided to make em work.
Rear was easy peasy. Bolt in, just swapped to a 1/2" bolt on the top.
Front took a little more figuring. I ended up cutting the bottom mount off the original shock. I cut a piece of 1/4” plate and welded across the mount. Tapped two 3/8 thread bolt holes. Cut some 1/2" aluminum tube into spacers for the correct height. Bolted the shocks to the adapters, painted it black, threw it all back in the truck. This actually worked out great because the front shocks were about 1" shorter than stock plus I have cranked keys. This extended the shock roughly 2" making the length about perfect.
By the way, if you all haven't seen em... Check out the Diablo Steel Demon circular saw blades. I use these a ton for metal fab any more. Saves a ton on angle grinder wheels, and it's way quicker and cleaner.
Not the prettiest job, but it works just fine for the Ugly **.
