I have a 51 chevy 3100 and built the motor a bit bigger than expected so I would like to change out the rear end or a possi track. Right now it has a 55 stock single track. I was wondering if there is a rear end I can get that is the right width to fit with out a lot of work. Thanks for helping.

Herbert, that would, of course, not be a 6 lug. If that's what you want.

We have used the Colorado/Canyon rear both drum and disc. Can't remember if the 2wd or 4wd one is the perfect width (61"). Has 6 lug pattern on 5.5 bolt circle. The Isusu Trooper is also 6 lug and just a tad narrow which can be cured with wheel offset or spacers. It has a Dana 44 so any gear ratio or locking/open is available at a good price. If you want one that is a straight bolt in where nothing has to be cut and re-positioned with no welding involved---it doesn't exist or it hasn't since 1949 when I first started.

Yes I want 5 lug so I will also have a bigger choice of wheels. I don't care if I had to cut and weld mounts to the rear end. I just didn't want to have to cut down on width.

A GM 10 bolt 60 1/4 inches fits well. Lots of after market parts to made it stronger if you need.

Ed, are the lugs the correct diameter for the old rims? I have seen some six lug axles in the junk yard, but the lugs were too big in diameter. I don't know what axle I was looking at.

14 bolt ff 6 lug axles are 6 on 5.5. Some GMC 1 ton are 6 on 7.25 'artillery' wheels.

What about the diameter of the lugs themselves? The threaded lugs.

You will have to check, however, most wheels have large bolt holes, you sure do not want .5" bolts. Check the holes in your wheels?
