No problems at all, GR starter only needs the switched 12V input to engage solenoid and big cable from battery as you have it shown.
Yes, I got that coil, has been working fine, no resistor needed, just went to the + with the BY and the positive wire for dist. On the negative I hooked into the old starter jumper wire.
Mine is a 73, so no igniter and the only item I got rid of was the ballast resistor.
I will note, I replaced the starter because the prior conventional rebuilt starter had hung up one night and acted funny. I got a GR as a replacement, and proceeded to smoke it two days later. It hung up and would not stop turning, had to pull the battery cable, everything was melting down. My friendly NAPA store replaced it, but the real problem was poor grounds. So for anyone working on this or messing about with starters and battery cables, clean them up and run the battery and starter ground cables to one bolt below the battery. I had mine separated just like the factory installation, short ground strap from starter to frame and then battery ground to frame below headlight. Rusty bolts, or whatever prevented a good completion of the power hungry starter motor circuit, the increased resistance nearly fused the copper contacts of the solenoid and made the starter stick. Was probably my problem all along, not a bad starter as I initially thought.
