Stop calling it a "FJ."
Hi All:
As part of finishing-up of the body tub swap on my '74 FJ40 I'm installing a full roll cage, and will be using 3/8ths inch bolts.
I've heard that Grade 5 fasteners will streech before failing, while Grade 8 bolts, though "stronger," are also more brittle. Don't know how much truth there is to any of this.
Opinions from those of you "in the know" regarding which grade of bolts to use?
Thanks in advance!
