yes, you can swap a 22r for a 22re. you don't even have to go to the ref. for it. i did mine about 5 years ago and took it into the ref. he told me i didn't need to because the truck came with the option of a 22re(mine's an 85). I asked him to look it over anyways if he didn't mind and he did. everything passed except for I didn't have the dash pot on the throttlebody. the swaps not too bad to do either.
