d100 manual trans question....

A stock 4 speed in a '68 truck should have a granny 1st. They made two different ones with different 1 gear ratios but both were non-synchro. Not sure if your bellhousing will work or not. They made so many combinations of engine, trans, clutch size, etc. Also, they went from hydrolic to linkage from '68 to '69. You'll have to take some measurements with you when you go.
