That will twist up like a stick of liquorice

The tube looks too thin, it looks like 2.5" 3" at the most and its a long shaft.

The long shaft needs to go up on tube size to give stability and the advantage of going up on tube size is you can run bigger and stronger joints

I suspect this will put a lot more vibration into the car than the original two piece and I suspect it will start to come apart at high revs.

I can do a calculation for you if you like, just give me the tube diameter and the length between the UJ centres


We've just quoted for a shaft for a Cossie powered MkII Escort and thats 1370mm from diff flange to gearbox flange and that had to be on a 3" swaging out to a 3.5" tube to get the critical speed up out of the potential rev range of the car.
