Re: Convert Allison 2 wheel drive into 4x4

high loc and low loc = 203 full time case unless part time kit installed .

and the ford case is if your doing driver side axle drop . our gm trucks are pass side drop .

you can do married if you want but try and keep it setup as a 2wd trans or see if someone can change the low range ratio to 1.96:1 to match a np205 and run a 205 t-case setup . and then have ORD mod the tail housing for the VSS over the speedo cable .
