I bought a summit universal drive shaft loop kit (part # SUM-G7900)
After some modifying here is what I came up with.
Drive Shaft Loop 1
Drive Shaft Loop 2
Drive Shaft Loop 3
Drive Shaft Loop 4
The inside diameter (width) of the loop was 5.25". this left a clearence issue on my R/T. We used a vise to press on each half and then heated and bent the sides back to that they 2 halves would line (bolt) back together.
The new ID was 6.5"
you will need to cut the rest of the pieces as follows:
off each of the other parts, cut a 4 hole piece off (used to bolt the 2 halves of the loop together) qty 2 pieces
cut 2 8" pieces off of the other side, this leaves the 90* bend as scrap.
you will also need an additional 4" piece
weld 1 8" piece and the 4" piece together in a 90* flat, goes on driver side.
the other 8" piece needs to be bent, 2" then 1.5" then 4" (the other 1/2" is in the bends)
these get welded to the sides of the top half of the loop.
the single bent 8" piece goes 1" above the split of the loop
the 8" + 4" goes 2.25" above the split.
only other pieces that you need are some spaces so put on the seat belt bolts, and 2 nuts to bolt the loop to the seat belt bolts
Notes: you should take measurements of your to get exact specs as this design might not fit every truck. Also, the exhaust heat shield had to be cut to reveal the passenger bolt.
