Afternoon chaps,
To clear this up, it really is a 1975 Spyder (not a Montecarlo), complete with full Zagato seats. Originally it came with a standard 1600 Beta engine, 2+2, front wheel drive. but when I found it two years ago, those who didn't know what it was would've let it sink into the gravel. Not me. Rest assured I'm saving as much of it as I can!
The 1.6 HF Turbo engine was indeed the one I found in it. Whoever had it last hadn't finished installing it and was clearly making a rush job of it. Missing all engine ancillaries (turbo, carburettor, hoses, you name it basically..), with loose bolts in frankly baffling places and completely seized at the cylinder walls. The most upsetting thing was that someone had clearly towed it out of a hedge using a tractor and had attached tow ropes to the rear wishbones, completely bending them out of shape and ruining the rear tracking (play a sad song here).
I'll attach a picture of it when I got it.
Cheers
Luis
