Sounds like a mess, what66!<br /><br />I'm pretty sure NAPA 18-2686 fits. Just to make sure, you'll get some spagetti, a couple o-rings, shift shaft seal, and the shaft seals.<br />The shaft seal sizes in the kit are:<br />ID OD Width<br />0.625 1.128 0.250 (Driveshaft)<br />0.750 1.375 0.250 (propshaft)<br />And the o-rings are:<br />ID Width<br />.245 .155 (shift shaft seal)<br />1.735 .135 (Seal carrier oring)<br />.215 .065 (shift yoke pivot oring)<br />Oh, and they give you a couple new L/U drain and vent screw gaskets.<br /><br />Good luck!
