1973 Fiat 850 Sport spider convertible

This is a 1973 Fiat 850 Sport spider that was my cousin's in-law's car. From the dates on the title they bought it in 8/1977. Drove it until the motor seized, then parked it in the garage and left it. She died last year and I got the car from my cousin and his wife. The motor did not spin, tore it down to find the crank and cam are froze. Probably lost oil pressure. The car is pretty much complete but has rust. Has 4-speed manual transaxle that goes in the different gears and neutral.Will not roll in gear but will in neutral.Odometer has 31,000 on it but suspect it has rolled over. There is rust issues, the frt fenders and rear quarters as well as under sill plates. The floorboards are good. The top mechanism is not bad. This car would make a good donor car. Thought I would see if anyone is interested in it for parts. If not sold will be scrapped. Has clean Indiana title.
