one ton dually questions.........
Just picked up a 68 C-30 ramp truck.
It has split rim wheels on it plus factory drum brakes with power assist. I have a set of dually wheels off of a 94. what do I use for lug nuts/studs? exactly where do I mount the ring that goes over the lugs? I want to swap to front discs. Are the 71-71 3/4 spindles the same as a one ton? Calipers etc, except for the rotors? If all the other parts listed above are the same except for the rotor, what do I use? Are the discs serviced separate from the hub/hat/spacer for dually wheels? The major thing at this point is fitting the newer wheels on the truck, drums stop it pretty good but with all the 3/4 ton stuff I have it would be nice to have front disc. I know I will need a new master cylinder and prop valve plus maybe new lines with new front brake hoses. |

Re: one ton dually questions.........
You need bigger studs (9/16" or 14mm) to run the newer wheels. You can buy studs for a '71 - '72 since they stepped up to 9/16" in those years. You can just bolt them on, but I wouldn't due to the weight of a loaded ramp truck. To my knowledge the 3/4 spindles are the same, but I haven't actually tried that. I know You can change out spindles with any year from '71 - '87 C-30 on your truck. You will have to use 71-72 ball joints and tierods, but you can use your control arms. Another alternative is swapping out the the compate crossmember from a '71 - '87.
NOW - Let's see some pics of that bad boy! Of all the musclecars and old trucks I have, I get asked to sell my ramp truck more than any of them. Here's mine.

Re: one ton dually questions.........
Bob, I will pass on to the new owner of my wrecker your info. I was looking to get some better mileage for long distance, he is using it as a yard truck, so I don't know. The rear was in good shape except for the high gear ratio.
