Ed,
Do we know how the original car was optioned ? M20 or 21 ?
The car that this trans resides in is a base car X44, no Muncie cable routing, speedo cable is definitely Saginaw or auto, 12 bolt PY code rear appears original, no dual exhaust frame plate, has a '69 Hurst console shifter and console (of course, could have been added). Factory A/C car (missing). I have not approached the owner about swapping the trans out, but he might be amenable. He knows it's a '68 trans to another Camaro.
Someone pulled a real number on the engine pad - ever seen a T073DZ restamp ? I haven't until now.
Regards,
Steve
