Getting the Wheeling Fever
I have a carberated '85 toyota truck regular cab and i just got my new drive shaft for the front but the bolt pattern on the flange of the T-Case doesn't match the drive shaft bolt pattern. both ends of drive shaft match the third member's flange. is there a real difference in bolt pattern on the T-case flange and third member flange. is this common and is drilling it out to match my best bet to fix it.Thank you for your help.

Drill it or get one of these, Marlin, All-Pro, InchWorm, Sky, and Trail Gear all sell them. About 35.00

Lots of places sell flanges with multiple bolt patterns (Inchworm, Marlin, All-Pro, etc) or you can do it yourself. Jay K explained how to in this article:

so what do i need do i just get a 10mm drill bit and use the bolt holes on the drive shaft as a guide for the new holes. will a regular hand drill have enough power. Are there any techniques i should know before i do this. thanks

Regular hand drill works fine, clamp the yoke flange to the output flange and drill away. Stop drilling when the bit goes through the flange. <img src="/forums/images/graemlins/kewl.gif" alt="" />

Yes, clamping the two flanges together and using that for lining up the holes works well. Put the new holes midway between the old holes. Also, drill one hole, then put in a bolt before drilling the other holes. Best to do one hole at a time so you keep things lined up.
