1987 gmc c1500

[Jeffp1979]

Hey guys been lurking on this site for a while, lots of good information and some great trucks. I picked up a 1987 GMC a few months ago, all stock except for some 30x9.50 15 tires on white wheels it is a long bed tan base truck I think although it did at one time have belt line molding. A/c is cold heat is hot 4.3 with a TH 400. I will post some pics when I get it to the house going to be a simple refresh looking for some rally's maybe, or just repaint wheels and polish caps, also thinking of a two tone. Only major problem to deal with right now is 2.73 rear end too high for me looking to go to a 3.42 or lower to pull my tractor and stock trailer still have to put gooseneck in. If I had a 3/4 ton rear could I put 3/4 ton front on like the old Dana 44 I know mine is 2wd but can I just replace with 3/4 spindles? Also anybody have some good factory two tone ideas just thinking out loud.
Thanks
