Does anyone have info on replacement wheels from a 16 inch split rim, to a later one piece rim. What I found so far, do not clear the brake drum.....As a second option does any one have a real nice pair of split rim wheels for sale..Any info greatly appreciated....Thanks

Need more info, Year? Axle type?

1970 - Not sure how to identify axle other than code in glove box: GE6 or G86 No spin. After trying several different later type wheels I find they are all to deep. I need 4-1/2" from back of hub to outer lip of wheel. The pilot hole is 4-1/2"

You should be able to run any GM 8 lug budd style wheel up to '87 to late 90s. Bring you tape measure and visit your local junk yard. I had a 1969 gmc k2500 that i switched over to'86 wheels no problem.

I wish that were true...on a 1970, I am destined to use the original wheels w/outer ring. There is Hub Centric, & Lug Centric, there's the depth of the hub, the outer/inner wheel lip, then the inner diameter so that the wheel clears the brake drum. Then there's the size of the lug hole, & is it flat or tapered.... Getting quite an education...which brings me back to my original question....Is there a one piece rim that replaces a two piece or split rim?... As a side bar, there is another whole issue going from a 750x16 bias belted to a radial tire....I am told its not recommended to use radials on two piece wheels, something about the bead.....and on & on....

I bought the rear axle from a '70 one ton because it had 4.10 gears and put it under my '57 one ton. http://i305.photobucket.com/albums/nn214/jfnar/57%20chevy%203800/70-1-ton-back.jpg
I'm using an adapter to run dual type wheels as singles. http://i305.photobucket.com/albums/nn214/jfnar/57%20chevy%203800/DSCF1040.jpg

The only difference between the '57 axle and the '70 axle was the length of the lug bolts (due to the '70 having single wheels) and this 1" thick spacer which I assume was necessary to allow the 16" single wheels to clear the drums. http://i305.photobucket.com/albums/nn214/jfnar/57%20chevy%203800/DSCF1146.jpg
I had to modify the adapter because it had 5/8" studs but I'm now running the original 19.5" dually type wheels. I think that with longer studs I could run my duals on this axle with no problem.

So that I'm understanding this clearly..you speak of an adapter, then a 1" thick spacer, is this that new piece? Is the purpose of that adapter to bring the wheel out so it clears the brake drum? - Where did you get that adapter?... Thanks

Is the 1" thick "spacer" you speak of just the hub? In the pictures I only see the think black bolt on dual to single adapter, not a spacer.

Here's the '70 axle. The part that I'm calling a spacer is part of the hub. http://i305.photobucket.com/albums/nn214/jfnar/57%20chevy%203800/DSCF1146.jpg
Here's the '57 axle. http://i305.photobucket.com/albums/nn214/jfnar/57%20chevy%203800/DSCF1147.jpg
They're identical other than this spacer and the length of the studs. I think the spacer was necessary to run 16" single wheels.
The adapter is to bring the wheel out so that dually wheels can be used as singles and give the correct track width. The adapter is actually intended to be used on the front hubs to convert single wheel trucks to duals. You can google wheel adapters and find them in several places. Here's one: http://wheeladapter.com/dually_adapters.php
I got these because I was not able to find 19.5" single wheels and I plan to put a 9' stepside bed on this truck eventually. I think it will look okay with the dually wheels as long as the track width in the back is close to the same as the front. As I stated before, the adapters came with 5/8" studs so you'll either have to drill out your wheels or change the studs.

It's still not a spacer, it's just two different ways of attaching the drum to the hub, called outboard and inboard drums.
Outboard the drums slip over from the outside same as a wheel fits on the hub.
Inboard drums are on the inside with the studs pressed through drum and into hub.
