Dual front disc brakes -‘77 R100/7

[tlangman4]

Hello-

I recently purchased a ‘77 R100/7 with the stock single ATE caliper and looking to update the front brakes to a dual setup up. I have found a set of forks for dual Brembo calipers.

I haven’t been able to find detail regarding possible differences in the fork sizes between my ‘77 and the models which utilize the Brembo’s.

Is it correct to assume that I would need a switch to snowflakes plus axles, but can use the same triple trees?

Thank you for any feedback!

Fork sizes

Brembo forks from a older than 85 R100 or R0 bike will interchange they are the same length and diameter. The Brembo forks from the R65 and R45 will not fit. St.
