I have a 97 f150 4.6 with the 8.8 front and rear...... what spline are they? is it 31 front and rear?

 

28 front and 31 rear

 

So this wouldn't work for the front?

No.

 

Then what is a good locker for a good price?

 

What about a mini spool up front?

Boom as in good or bad?

 

As in very bad. mini spool doesn't allow any difference in wheel speed in 4wd or not on these trucks. You'll break something in the front(cv or diff itself) if you drive on the road. Might get away for a while is you stay in the mud/snow year round aka trail rig only
