Well, you are correct on this... In addition to 71-72 there is also 73-74 G-10 vans. These (71-74 G-10) use the 70-78 camaro rotor & caliper. So, there are numerous outlets for big brake kits. Bear, SSBC, etc...
There is a difference between 71-72 & 73-74 G-10 Spindles, the outer tie rod mount is different. It's thicker where the taper of the outer tie rod goes thru the spindle.
As far as the outer tie rod ends used:
71-72 G-10 is same as 71-72 C-10
73-74 G-10 is same as 73-74 C-10
If I remember correctly, the 73-74 tie rod hole is thicker top to bottom.
In 75 G-10 went to 5 on 5 bolt pattern.
I have a set of each 1) 71-72 G-10 van spindles complete & 1) 73-74 G-10 van spindles complete.
My plan was to build a race truck style build and use cross drilled rotors that are commonly available for 70-78 camaro rotors as well as aftermarket race caliper (wilwood, strange, etc...) I actually had them mounted on a rolling frame for awhile with 15x7 ralley's for about a year before I changed my vision for the project.
P.S. yeah, I've worked in auto parts for 22 yrs, 5 yrs of that at NAPA, so, had lots of time to research stuff like this...
If you wanna talk using stock parts to come up with 6 on 5-1/5" disc brakes PM me, I've researched that as well, If I remember SCOTI helped me on that deal... that was awhile back, If SCOTI doesn't remember helping out, I'll take FULL credit for the research.... Just kidding SCOTI.
