" From: Frank Swygert <farna@xxxxxxx> " " [] " " The problem with changing from the "big nut" driveshaft is the pinion " shaft. I'm not sure the splined end is the same diameter and spline " count as the later open drives. The pinion shaft also isn't drilled " for a bolt to hold the later model yoke on. Any machine shop can " remedy the bolt problem, you'll have to check the splines with a yoke " from a later model. Check the length also -- the big nut pinion may be " a bit longer, but I think it's the same length as a later pinion " shaft. The bearing diameters need to be checked also. i'm sure i read somewhere that the 'big nut' pinion -is- longer, with a longer spline. but everything else was the same though. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
