Bucket Seat hex bolts needed (2)

I think sleeve measurement is closer to 5/8" wide than 1/2" as orig posted (duh) and note: the threads are course not fine. The ones I got from Roy are too long, sleeve too narrow with fine threads (seat belt bolts?). I will try to modify these- see if I can re-thread to course and add a sleeve washer to make up difference if I cant find right ones but keep looking!
Thanks again Roy- got these bolts in 2days! I guess it taught me to never trust my eyes (espec as I get older) as these bolt sleeves looked longer than wide. Measured length and just took for granted width...
I repeat: duh
