Unsure of the value of it. I haven't looked in the crate for probably 10 years but it looked great then. Oddly it appeared to have one different piston if memory serves me. I can post pics and more if there is interest. There is a part number on the crate- I believe it was a late seventies model 350. Located in Iowa. I would be interested in trade for a "late model T10 transmission. Thanks for looking.
