My 12boat tubes are welded to the centersection.
Priced through Jegs, for 12boat:
30spline spool ; 150
30spline S/S Axle kit with C-elim stuff; 430
Lightweight 33spline spool ; 189
33spline S/S Axle kit with C-elim stuff; 610
...or skip-it, cash the 12Bolt, and call Moser...for a moly-tubed Dana60 housing.
-----------------------------------------
Run Nov 11 with stock 12Bolt Axles. My front wheels are toed-out real bad..no wonder it's a logger's ride at mid-high track. Front-End alignment and cool will probably sit me in the high 11's.
-----------------------------------------
Then full-tilt upgrade this winter.
