Have you tried NAPA
I was also thinking of changing the perches because of the gap. However Napa does have the 7/16" x 3"x 7.5" u-bolts. They are long enough if you don't want to drill the perches. Part number is 650-4075. Just bought two more on Tuesday for the other side. . As for the steel strap strap where can you buy this? I used the poly pads. Oh yeah chevy2only also has the u-bolts. Part #27017.(7/16 DIA X 3 1/4 WIDE X 7 1/2 LONG THREADS ARE 3"). Hope this helps
