Let's Build A 1 Ton Crew Cab 4x4 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

On my 76, I used 2wd rear spring/shackle hangers, a DIY4x shackle, and no block to get my rear suspension up. This required cutting the spring perches off the rear axle to reset pinion angle though. It was cheap and works. In the pic, I still have to make or install the lower half support bracket for the hanger.

Like this.

So it's basically like a sliced a slot into the engine mount bracket for the frame rail to slide into.

Thanks for that. I understand now.

I went out and tinkered for a minute last night.

Here is the engine mount slotted. The 4wd frame is 1/2" taller in the area that the engine cross member mounts. More bad news is where the front cross member that the brake proportioning valve mounts to is like 6" tall from the 4x4 but the 2wd frame rail is only about 5-1/4" tall in the area it should mount so that is going to be interesting as well...

I was installing my new U bolts and found some issues I need to resolve. Always something. I need a shorter stud for one.

Still need to find somewhere I can buy just 2 cheap U bolts that are square, for a 2.5" wide leaf spring and 13" long. These will temporarily mount the blocks until I can build my rear hangers. I need to be able to roll this thing out the shop soon to clean and paint the frame.

Negative. They are from Ebay. I found this set for over $20 or so less with free ship. Seems like they would be perfect for 6" springs or larger but my 4" springs aren't that much thicker than stock springs. If they were threaded all the way like ORD's then they would work fine. I may take them out and cut more threads on them if I can't find a cheap replacement.
