First time on an automotive forum...so please be patient. Lol!

I just purchased a nice little ‘89 Toyota pickup. I have always driven Toyota. I am retiring my ‘01 Tacoma after 408,000 miles and 17 years in the log woods. I also own an ‘85 running on 37’s. Anyway...my question is about swapping the IFS system off my ‘89 and using my ‘85 axels. I have been trying to do some research on different kits offered for the swap and I’ve run into more questions than I have answers. If someone could point me the way or help with a few suggestions I would greatly appreciate it.
