Fitting a 1275....

[linearaudio]

There are, I believe, two clutches for the Triumph box. One is 6 1/2" dia with something like 9 splines. The other, much more likely, is 8" with around 20 splines, so easy to tell the difference. The bigger clutch mates with the Marina flywheel, and is therefore probably what you have. More likely to find it listed under "Dolomite" than "Toledo"!

And yes, it is high time some of these subjects were hived off, eg 1275 engine to minor box, cam choices/ pitfalls, 940 head fitment, "Big W" brake fitment, Disc choice/ fitment/servo etc, Rear axle ratio versus 5 speed gearbox, etc etc...
