AC Delco shackles

Something I did recently that you may find useful...I had two full sets of a-body shackles, and on all four the pins were so rusty I couldn't use them. But the "dogbone" plates were fine. I drilled out the dogbone holes to 1/2" and dropped in grade 8, 1/2" shoulder bolts 4.5" long and made new shackles. I suppose you could get fancy and tack the bolt heads on one side.

I'm using poly bushings, I've driven the car once since then and it sounded and felt alright. Its really no different than using adjustable shackles.
