Guaging Interest Lower A-Arm Bolts

[AntiBling]

Just wondering how much interest there would be if I did a run of Lower A-Arm to Frame bolts.  I know when I removed mine they were really rusty and the one was damaged beyond repair trying to remove it. 

I know one guy makes them, but one thing I didn't like is he makes them out of grade 8 and if there was a pulling force exerted on the bolts that would be fine in my book but I made mine out of grade 5 since there is a shearing force, a harder bolt is more likely to shear.  Plus grade 5 would be cheaper.
