1950 GMC 3100 rear end advise needed
:gmc2: I just got a 1950 GMC 1/2t SB 3100 w/ sometype of a 6lug drum rear end thats already an open drive line. Its works great but I would like to switch to a 5 lug wheel pattern,so what rear end would bolt right up to my new 1950 GMC w/ minimal if any modifications. I would like to remain drums all the way around. And also can I just switch to 54 drums in order to change the front to a 5 lug wheel pattern and will that be a direct swap in the front:gmc2:?
Thanks for any advise given to me in advance |

If there is a 5-lug rear that will simply fit without modifying the mounting pads I don't know which one it is. Quote:

I prefer a disk brake conversion because I believe it results in a safer vehicle using easier to maintain parts and if you shop carefully does not cost a lot to do. |

Here's a copy of an article that was posted here a few weeks ago. I'm not aware of any direct bolt on replacements for the front that won't require the use of an adapter, but there are a ton of aftermarket kits available for the AD.

Thanks for the info. Then it must be a GMC 100 I thought it was a 3100 series. I really dont want to have to do alot of mods to swap the rear end. I was hoping there is a simply drop in and bolt up 5 lug rear end. As for the front didnt realize alot also needed to be done. I thoght I could just slip on a 5 lug drum,am I wrong? Thanks again |

The stock rear was about 62 inches wide wheel mounting surface to wheel mounting surface. If you get much narrower than that the tires will rub the bed, much wider and they will stick out of the fenders. So you want to find a rear that will put your wheels and tires inside the wheel well with enough clearance both inside and outside. Quote:
I've never swapped Huck brakes but its possible that 5-lug Huck drums and hubs would be almost that easy. Those would be '49 and '50 Chevy car brakes. I've not tried this particular swap but that could be easy to do without the backing plates though you may still need to match the bearing sizes. I last did this type of swap in the middle 70's and I'm a little fuzzy on some of the details especially the bearings part... If I'm wrong I'm sure someone will come along and correct me. Like I said before, I prefer the disk conversions for the front these days. I can't imagine doing all that work and still having drum brakes. Especially Huck drum brakes... |
