    I have a NP205 t-case that I need to drill and tap the side of the case so I can put the brace that holds it the frame on. Is this something I can do or do I need to have a shop do it? Or do I just need to trade it for one with the holes?

    I wouldn't drill and tap the side of the case. It is made of cast iron and is strong, but its not the thickest on the side and your not going to get many threads out of it. What drivetrain are you running? Do you absolutly need this? If you are set on using a brace, I would go to an existing bolt before bothering to drill and tap the case, maybe to one of the front output rear cover bolts.

    If the pad is there you can drill and tap the holes. (some cases are drilled and tapped some are not. I've seen them drilled but not tapped too)
    If you have a good 1/2" drill and good bits and have a 5/8" tap.
    and a way to secure it so you are not chasing it all over the shop trying to drill the holes have at it.
    Drill and tap about 5/8" or so and use a stud kit.

    Let me post some pictures. I am not really trying to drill right in the side. There a raised thinker spot that in the T-case that came out of me blazer had two 5/8" holes drilled in it for this mount.
