If you can use grade 8 do so.. if all you can find is grade 5 it will be ok as long as EVERYTHING is grade 5.
And yes you can wirewheel the tank if you want without blowing anything up.

Agreed, use matching hardware. Grade 5 is enough. Those little 3/8" rivets did the job for how long? And they were how hard to get off?
The big thing is torquing them to correct spec. Grade 5 3/8-16 is 30 ftlb. Grade 5 3/8-24 is 35 ftlb. The Grade 8 numbers are 45 and 50 ftlb. (Those are dry numbers. Do not lube the threads when you install them.) If you seriously under-torque or over-torque them, they will ultimately fail.
