I used Dexstar am20766 trailer rims on my 1 ton. I haven’t put the hub cap clips on yet, but have read that it’s simply a job of riveting them onto the rim. They are 16” rims and I run 215/85/16 on them. You will lose a little bit in tire height but it sure rolls nicely. These were a very good modern alternative. Go to their site and look up FAQ about this model rim. You will find a lot of info regarding their fit on 3/4 and 1 ton chevs/gmcs from these years.

Plus they look original...ish.
