I do have an old set that have been in the back yard for about 10 or more years.
But lets not get carried away here.
5.71's aren't the most desired gears, but for the price it would give a better crawl ratio without any lower Tcase gears.
Won't do much for hwy speed, but she should trailer it anyway.
I need to look, maybe I can find enough parts to put them together with out even install kits. I think I may even have a welded carrier.
