a friend of mine gave me an m20 he got with his 70 ss when he bought it in 84 and told me the he bought it from gave it to him and told him it came with the car when he bought it in 74 the car had an m22 in it so niether used it and my friend said it was shelled as you could hear parts rattle around inside ?? so i pulled the side cover and 4 gear forks washers,needle bearings,roller bearings,new side cover gasket etc. fell out??
looks like someone tore it partially apart and threw all the parts and some extras(bolts) back in it??it has an 010 main case
a 584 tail case
any idea what it would be worth even as a core? it looks clean inside and turns freely now that all the spare parts are out of it and the gears look new!!!
