So I'm sitting here on the side of the road with my front u-joint for the rear driveshaft broken in pieces waiting for my buddy to come tow me ! And I figured I have an iPhone and I can surf the web ... Why not start reachering where to get the parts for my t-case ? Ran the t-case low a coupple of weeks ago and now it's leaking from all the seals and making noise

...So guys !!! Where is the best place to get the pieces to rebuild this t-case ? It's my 79 c10 short bed 350/th350 and I belive 204 t-case ? Any help would greatly apricated !!!

If it's a part-time 4wd it's a NP205 if it's full-time it's a NP203. check Craigslist and bone yards. Shipping will kill ya if you have to have one shipped. If you can get parts they are easy to rebuild. They are tough as nails.

Ok ! ... So I got under there and checked it out. The rear driveshaft yolk coming out the t-case has some up and down play(aprox1/4in.) and the rear diff gears are gone !!! ( can turn the driveshaft aprox 1/3 turn) !!! So it looks like I need atleast a bearings in the t-case and gears in the diff ! I think that I've got a 14 bolt and 3/4 ton front 10 bolt out of a 81 that I can prolly get pretty cheep(800$ or so) u guys think I should go 3/4 ton or put a Detroit locker in the 12 bolt ?

dude $800 is way too much for a 10 bolt and 14 bolt even if they are a matched set. You shouldn't pay over $400 for that combo.

I just sold a 74 k10 for $100 with both axles in good working order. It's the truck I have been advertising on here for the last 6 months. I kept the 350/203 as spares for my truck. There is a sm465/205 combo in Boise Craigs list for $250. There are lots of K10 series axle up here for a lot less than $800. You can probably pick up a complete K20 truck for that. Economy is forcing lots of people to clean up their back yards. Shipping would be a bit but you might be able to find someone heading to Vegas for a vacation that would toss them in the back of their truck for some gas money. If they are truly getting $400 an axle I may be starting a new business.

I agree on the price it's high. If it were a 14 bolt/dana 60 and had a locker and the right gears, $800 would be good.

tomtuna1978 · 10-11-2009, 07:45 PM

i havent really spoke price to him yet for the axles. that was just what i was expecting. the only thing about swapping the 14 bolt is i just bought new 6 lug rims for this thing ! is there any 14 bolts out there that are 6 lug ? ... im just thinking about puting a detroit locker in the 12 bolt with some c-clip eleminators !

**jerry moss** · 10-11-2009, 08:22 PM

there are some 14 bolt 6 lug diffs in later trucks, still semi floaters but beefier than your 12 bolt.

tomtuna1978 · 10-11-2009, 08:35 PM

will they bolt in ? if not then how much fab work am i looking at? im using this truck for some wheeling and light stuff. im not going to go do any hard core rock crawling or towing big heavy stuff. im still thinking about puting a locker in the 12 bolt.

msgross · 10-12-2009, 03:01 PM

you won't like the locker on the road though.. I would buy a cheap 12-bolt with matching gears for your front and then add a posi-trac of some kind.
