Ok I bought an 87 K10 for a project truck a few months ago. It has a set of 15" rims with 45" tires. It has a 4" suspension and 5" body lift on it. It took a little work on the motor and rebuilding the trans, but I got it running. Well that is when I found out that I had mismatched gears. It has 3:42 in the rear and 4:56 in the front so needless to say when I put it into 4WD My rearend jumps like hell. Well I have been shoping around for a new rearend/gears when I found a 77 LWB 3/4 ton 4x4 that had no rims or tires, and didn't run. But eveything else worked i.e: TC, 4x4, brakes..... to do was go and get it. So I bought a set of old rims and tires from the junkyard just to go get it. Know I have a good motor, trans on the 87 that I can put in the 77 with no problem. My issue is that my 15" rims are 6 lug but the 77 is 8 lug. Is there any way that I can get to use these rims or am I going to HAVE to buy a new set of rims if not rims and tires. Is there such thing as a 15" 8 lug rim? That is my issue Please help. It seems my pics are to large for me to put them on. How do I fix that????
