[68Dually]

I bought a 1968 c30 Dually with drum brakes all the way around it has 16" split rims on the back I bought newer style 16" rims and they won't fit over the drum in the rear and I want to change the front to disc also. Mi have the chance to buy an 1982 stake body for cheap can I switch everything over in the front to get disc brakes and hydro boost set up will it all fit and I would like to switch the complete rear so these will fit does anyone if it will work before I buy this other truck thanx

Im doing a dually swap on a 72. Was told the 80s model stuff would fit. Not sure if you would have to swap the whole front crossmember or just control arms and spindles....

My understanding is that the front suspension complete cross member is pretty much a drop in. I'm getting ready to do a whole cross member swap in my 69 C30. I understand a couple holes need to be clearanced to make it work but that's about it. 73-87 parts are cheap and easy to find as well. The tie rods, pitman and idler are the same 1/2 ton through 1 ton so those parts are super easy to find. I found a complete early 88 (87 style) front cross member complete with new ball joints, shafts and brakes for 300 bucks. I couldn't buy the parts for that price. The heavy stabilizer bar is a bolt in too. You'll have to check spring perch width on the back. I don't think they are the same. It's not that difficult to change spring perches. Just a little welding. My C30 already has a 14 bolt in it.

Do you have an 11,000lbs rear axle? Late model 16" rims fit over the H052/72 rear drums, I have them on my '72

How do I know what axle is in it

if it's an 11000lbs axle it will be marked on the SPID, also you should have a rear axle at ground GVWR of 11k on the plate on the driver's door pillar.

There are some differences between the housings also so you could tell, if I remember right, but I'd have to go look at my shop manual

The 11,000# axle is 10-lug. It's a larger truck axle. I've never seen Budd wheels with smaller holes than GM hubs. I've seen Budds off other makes have larger holes,though. I bought chrome Budds for a '70 C/30 that had the same rear this truck should have. I never gave it a thought,they never asked anything before ordering,not even sure I told them what brand of truck I had,just bolted them on
