Too many variables. Get out the tape measure. Give Rocket a call.

^^This is the kind of out of the box thinking that this forum is best at.
I would guess a 37" shaft would work.
Or swap for that B/G car like the above posted said :D
Falcons and Berts are the same length as the Saginaw 3 and 4 speeds they were developed to replace. The Brinn(most latemodels) are 2" shorter so minus 2" from what ever Rocket set up book says. I'd guess 37" as I think most SLM are 39" with a Brinn,Quote:

Correct. I spoke incorrectly.Quote:

I bought it used but had a tooth broken on the input shaft and the previews owner complained of it jumping out of gear. I ground and smoothed the gear tooth and adjusted the shift forks and shifter detents and it's been flawless for me. I have a spare rebuild kit but it's still on the same set of clutches.
XR1 with std Gen2 Bert trans takes a 37-37.5" (37" preferred) shaft. Gen2 is 21.752" from bell flange face to end of tail shaft. Measure or find your trans length and cypher! No idea how long a Falcon Trans is. I do believe they are rather long, so I'd ESTIMATE a 34-34.5" shaft in an XR1.
The standard slip-yoke Falcon is about the same length as the Brinn transmission. A Falcon roller-slide is the same length as any Bert transmission, which is about 3" shorter than the Brinn. So depending on which Falcon transmission tail shaft configuration you are using i would go with what CCHIEF described.
Original Brinn is 21.5" long
