Re: 1976 CCSB Duramax Project #trucknamedsue

sorry about picture size, I'll work on getting future uploads right..

after I machined the rear hub bores and sleeved them, I had to redrill the pattern. Luckily a friend of a friend builds top fuel dragsters and let me borrow his jig-bore bridgeport for the afternoon.

Put the hubs in a nice rotary table, lined up everything and piloted, drilled, spot faced, and reamed each hole in the gaps of the existing holes.





I didn't control the spot face depth well, on purpose, so to make all the studs fit the same I machined individual thickness spacers for each spot. The lugs normally fit through the reinforcement ribs on the hubs. Since they are in the gaps now, I needed to make up this thickness.



all installed and on the truck. I had to make new ABS tone rings as well, 60 tooth instead of 48. I'm not sure I have pictures of this handy. If anyone wants to see how I made them, I can dig.





machined a plug to plug up the factory oil return from the pcv filter. I had to ditch the pcv filter to clear my tie bar on the coil buckets.
