I had a hard time finding 9/16's bolts. I needed some for a shock mount on my bronco and couldn't find the size i needed. Even at Wilder's, I had to go with a grade 5 threaded rod. Wasn't real happy about it, but at least it was grade 5.
I needed 9/16 x 5" bolts for my 63" chevy spring swap. They had them in grade 5 and 8. It's a striaght shot up 85, about 45mins from Charlotte. They have had all the odd ball hardware I've needed for my rig and are very reasonal on the price compared to others.They have been very helpful to me.

?? Just last weekend I was at Lowe's trying to get 9/16ths bolts, only had 1-2 sizes and they were coarse thread.
Only F-ing SAE threads on an 80s 4Runner are for the F-ing rear seatbelts and holes in the rollbar (since they're intended for shoulder straps)... and of course they're fine thread. Thank you very much US safety laws.
Slim pickin's anywhere but a fastener store.
go check out your local john deere dealership, should have just about any size you need. straight bolts, u-bolts, tapered headed, and hex head. just get to know the parts guys and find the one that will take the time to look whats in the EPC. might have to order them, but machine down ordering will have them at the gate by 6am the next morning.
