Hi fellows!!! A while ago I asked for replacement for frame rivets. In that opportunity several guys adviced me to try and not remove any rivets. Well, the frame was worst than I expected and had to remove the engine cross member and the next one. I'm wondering which would be the best replacement: Hex flanged bolts (grade 8)unfortunately I have just found coarse thread or ferry cap screws (12 point head with flange) this is usually ISO 12.9 class (higher than grade 8). This I found in fine thread. The flange in the hex head is bigger (13/16") than the ferry (9/16"). Which variable is more critical, the area of the flange (to distribute the force), the grade or the thread (so it won't slip). Thanks for any ideas.
