so this may sound stupid but what is the front spline count on a 1979 toyota pick up 4x4?
i thought it was 27?
but if it is how does a longfeild 30 spline berfelid fit?
or the birfeild elmator kit work?
ist here anything that has to be changed on the 3rd?

 

At the diff - 30 spline

At the birf - 27 spline

At the manual hub - 30 spline

Longfields make the 27 spline section where the outer end of the axle and the birf go together 30 spline.

BEK replaces birfs with a u-joint (30 splines are stronger)

Nope.
