I'm buying a 47-54 truck axle & springs, I think its out of a 1950 3100. My question is... Will the 49-54 chevy car spindles that Speedway sells fit?
That's exactly what I did on my axle. Used '55 Chevy car drums and the hubs from my '60 wagon, but probably gonna change them to '61-'68 Impala hubs 'cause they're roller bearing.You can also put Chev 49-54 drums right on the truck axle. They use the same bearings and races that the trucks used. So you've got options for either drums or discs in 5x4.75"
Yes! Look for a more complete axle. It will probably be cheaper than buying everything your axle is missing. You could be in several hundred more if you buy part individually.Yes, 3100 is half ton. If it's a six lug, it's half ton. You'll have to buy a king pin kit which will have everything you need mount the spindle to the axle. The pins may have to be "fitted" to the axle, which may require going to a machine shop depending on your resources.
Have you looked for a more complete axle? Or maybe spindles on eBay?
