I have a chevy front/rear end I bought many years ago and do not remember the exact year. I want to put it under my '86 Silverado 1/2 ton. The 3/4 ton rear end has a 410 ring gear with open carrier. I want to put in a positrac.
Any suggestions on brand and model number of positrac? I like 4 wheelin and pulled it with the 1/2 ton suff. The new 3/4 stuff needs to be tuff enough to hold up to a tractor pull one a year?
