Replacement was perfect, and shipping was quick. Pontiac parts are extremely difficult to come by, so get them while you can!.
Bolts were extremely effective. On my AMC 360, I installed the 727 flexplate with spacer. Bolts are well-made, have a tight tolerance, and are well-torqued.
Also fits a 292 GM inline 6-cylinder engine.
These were used to replace the ones that came with my Amc 360. Because the head is slightly larger than the stock bolts, it worked great with a small modification to the transmission inspection cover.
On a 1977 Pontiac 400, these were installed. It was difficult to come by these. If you need flex plate bolts for your Pontiac, get them while they're still available.
I'd buy it again and tell everyone about it!.
