I have just got back in from checking my '94 Indian Bullet frame.
The swinging arm mounting plates have additional plate reinforcement welded on the inside, which I'm guessing correspond roughly to the Redditch swinging arm thrust washers, the distance between the inner edges of these reinforcing plates with the swinging arm bolted in place is 194mm, as accurately as I can measure.
The Indian swinging arm pin is 1/2" diameter, but the 50's Bullet had a larger O/D swinging arm pin, 9/16". On my later framed bitsas I used the later Interceptor thrust washers, part no. 33787, the Interceptor uses a 1/2" diameter pin and metalastic swinging arm bushes.
More modern Indian Bullets have metalastic swinging arm bushes with protruding inner steel bushes. As far as I can tell these bind against the inner reinforcing plates when the swinging arm pin/bolt is tightened up, with clearance for the outer bush and its housing in the swinging arm itself to pivot against the rubber in torsion. If your G2 frame is narrower, you might be able to shorten the inner bushes SLIGHTLY providing you don't lose clearance.
Another thing to watch for is the width of the swinging arm where the bottom shock absorber studs are fitted. On the later Redditch frames the bottom mounts are further apart than on the Indian Bullet, not by a spectacular amount, but enough to have slight fun and games shortening bottom shock absorber bushes and fitting a spacer behind each shock absorber bottom eye to get everything nice and vertical. I am hoping in your case that the pre-56 Reddich swinging arm and the more modern version from India are more alike in that respect.
Is the plan to use an Indian Bullet back wheel? Ease of availability, etc...
