There is no such thing as a frame "Swap" other than a 49-54 Chevy, those will swap with yours. Any S-10 or other frame takes a LOT of fabrication, there is NO "bolt in" or anything even close. It's no different, not one bit different than saying "is there another fender that will swap?" Sure you could put an S-10 fender on there, with enough modification right?
A frame "swap" is really a money swap, or time swap. You are swapping money and time for different frame that's all.
There are ZILLIONS of bolt on kits for those cars. Will it cost more than a wrecking yard S-10, maybe, maybe not. By the time you rebuild the worn out frame you modify to fit you could have spent the same money on a kit that bolts in on a weekend and you STILL have a very cool 50 Chevy Deluxe instead of a half breed.
That frame in your car, complete suspension and all is exactly the same as a 53-62 Corvette. Now a 62 Corvette isn't a bad car to drive is it? That is EXACTLY the same front suspension as your car, parts will inner change.
Think long and hard before you dive into such a project. Replacing rear end and the front suspension if you wanted to update it can be done at your leisure and it would be FUN. Changing a frame over from some other car would be a HUGE undertaking.
If you do decide to do it, I am looking for the front suspension you have in your car for my truck.
