Frame....How many rivets can I remove??

[Prathbun]

I am working on a 69 frame. Will I be compromising the frame strength by replacing rivets with bolts?? I don't want to remove every rivet but I have removed the rear cross member (gas tank relocation) the reinforcement plates over the rear frame arches (for rust clean up) and I have moved my transmission cross member.

I will be replacing each rivet with grade 5 hardware. I'm also wanting to see if I can have the frame lined up (or straightened to true) at a local frame shop before final assembly. Ultimately I'll be painting or powder coating the frame.

Any input?

Thanks in advance!!!
