‘85 915 into a ‘72 T - Help Pls

[JonoF]

Dear Longhood Experts

I am looking to do a transmission swap on my 1972 911T. I would be grateful for any advice you can share for a problem I have stumbled on.

I have a viper green 1972 911T, fitted with a 2.7L and magnesium case 915 from a ‘74 911. The control arms are original steel control arms for the ‘72 and the trans is fitted with course spline 4 hole flanges.

I recently bought a rebuilt 3.2L and alloy case 915 from an ‘85 911. The trans has fine spline 6 hole flanges.
The problem: the fine spline 6 hole flanges (from the ‘85) are thinner and have a smaller bolt pattern than the course spline 4 hole flanges (from the ‘74). This means the axles, CVs, and control arms can’t bolt straight up.

The question: what is the easiest way to get the alloy case ‘85 915 in the car? Do I need SC/Carerra control arms and axles? Or does someone make CV flanges that would bolt into the newer 915 to be able to use the original CV shafts (eg a fine spline, 4 hole flange that has the larger bolt pattern)?

I am hoping this is no reinventing the wheel as I’ve seen plenty of long hoods cruising around with SC/Carerra drive lines.

Thanks in advance for any advice you can share.

Cheers

Jono
