I went to four different stores & a Big-O tire looking for a centering pin and bought a few 5/16th grade 8 bolts just in case I couldn't get one.
O'Reilly's didn;t hve the 5/16th pin that came with my leaf springs but had the next size up a 7/16th. Turns out that was the correct size and...
Made it back to civilization.
Jacked the cruiser up, loosened the u-bolts and hammered the leaf back in place. Took all of fifteen minutes.
Got a locating pin from oriellys to put on when I get home.
Thanks for organizing the run @brices123 :cheers:
