    I have managed to physically destroy my current NP208 in my '87 blazer. I have a 5" lift, 33's, 10-bolts with soon to be 4.56 gears. I spend most of my time in the mud, snow and sand, with a little rock play in between. Road worthiness is not an issue, this is just a weekend warrior.
    I knocked a hole in my 208, repair options would be for my to find a new front case and rebuild it, replace it with another 208, or a 241. What are the pros of a 241 over a 208 and what kind of installation difficulties are involved if I go that route? No shop in the area can seem to answer my question. Any help is apreciated.

    Without knowing what tranny you have, I would suggest you to buy the NP205 t-case and never worry about another t-case problem again. /forums/images/icons/wink.gif

    If you knocked a hole in the 208 you might want to consider stepping up to a NP205. You're never gonna hurt that case...

    I have a 700r4, I,m not sure if it will bolt up to a 205. Plus I am fighting driveline issues right now as it is. If the running gear gets any longer I'm not sure what I would do. I have already lowered my t-case 3/4".

    The 700R-4 is a 27 spline output just like the TH350. 205's were found behind TH350's so that part of the problem isn't that bad. The adaptor and output length of the tranny need to be addressed though. The upside is it will be shorter overall than the 208 or 241 and way tougher.

    If you don't go with the 205 my second choice would be a 241. slightly deeper low range plus there is a fixed yoke kit available. That will shorten things up some and allow you to run a CV rear shaft.

    Well since I've got to drop the tranny anyway to replace the front main seal, I guess it will be a junkyard 205, thank God for Pick-A-Part. Thanks for the help.
