Porterbuilt Stage 2 rear deluxe questions

[Calvin D.]

I have the Porterbuilt Stage 2 Rear Deluxe version which Im about to install on my 69 GMC short bed stepside with leaf springs and I noticed my rear end don't have the U bolt nest assembly mounting brackets on each end of my axle tube. I was wonder if Porterbuilt or someone make the brackets to weld to my rear end to mount the U bolts that came the kit.

Also once I install the C notch will there be any clearance issues with the wooden bed. The C notch bolts seem to stick up a little higher then the rivets that are originally on the frame, or will the bed rest on top of the C notch bolts I attached a pic of the bracket on a rear from the Porterbuilt site showing the bracket Im missing on my rear end tube.

thanks in advance
