Help! I am converting my 01 auto 4x4 to a 6spd, I pulled the transfer case out last night, It doesn't have the speedometer senser hole machined out in the tailshaft housing. I have been told the 6spd has no place for the senser. The senser was in the auto trans. Can I remove the tailshaft and open the hole up. (drill/die grinder), or buy a new tailshaft. Can I get it anywhere cheeper than the dealer. Ps the tcase is the hd model. Thanks Jason
