converting to 37 spline axles

seeker1056

gear head
seems everyone is saying to switch to 37 spline axles for my 80 - but no where can I seem to find out if it is a straight bolt in for my stock 35 spline dana 80 dually axle
Meaning do I need to bore the spindle or is it as simple as just installing the new 37 spline axles and spool
thanks

Axle and spool and it will drop right in.
 
Yukon 37 splines will go in a ford housing, but the 37 spline braniks needed just hair of boring, i actually used a modified engine hone to remove just enough. Not sure on a dodge housing.
