diggerpro Posted November 26, 2012 Share Posted November 26, 2012 My Compound case on my unishift transmission split and I need a replacment trans or parts to fix. This truck is so original I hate to have to resort to dropping a duplex into it but that may have to happen if I can't find one. Mine is a TRDL 725 out of a 1965 B61 with a 673 in front of it- Any help locating one would be greatly appriciated !!!!! Feel free to call me at 570- Four One Nine - 1099 thanks!!!
