The TR7 is a just an ongoing evolution of the TR series Triumphs and is an entirely conventional layout: front engine, to bellhouse, then to box and on to the rear axle/diff/drive. But imho the TR6 was better, had a better donk; the TR 7 had a 4 cyl somethinoruther, but the TR6 had a nice (mechanical) fuel injected 2.5 litre six which was a brilliant piece of work for its day.
 
TR7 was a fixed roof, but towards the end of its life the roof came off and there was an optional V8 (aka the TR8, or the TR7V8) and the V8 was something we here are very familiar with, I believe....
 
The X1/9 runs a 1300 cc Fiat sohc donk which is right behind my left ear and screams to 9000 revs. The body is a Targa and the hard roof comes off, and is stored in the front 'boot'.
 
Bertone made the tubs and FIAT fitted the drive train which was pinched from the FIAT128. The 128 was asedan with regular front wheel drive setup, and they transplated the drivetrain to the middle for the X1/9. There are tie rods instead of steering at the rear, but its always fun with the tyre guys:
 
'Can you do a toe in toe out on all four wheels?'
 
The X1/9 is a nice piece, but the FIAT running gear has a bad habit of failing...
 
Do a google and you'll find 'em.
