What type of support are you going to use for the np205.

Yeah good question. Where on the tcase did you bolt the second the xmember to Larry? What did you take that xmember from? I was going to customize something but maybe your route would be easier.

I had a 69 4x4 with a rockwell t-case and it had a factory second x member and look just like Larry's.

I am not convinced adding a tcase support will gain anything but add torsional stress to the transmission tail housing when the engine is under load while the tcase is tied down. I suspect that is why GM quite using the tcase support on the passenger’s side on 1973 and later trucks with the aluminum bell housing where older trucks with cast iron bell housings used to bolt the frame.

Now, a rod from the tcase to a bell housing bolt I would do if I could find one. Again, I haven’t ever seen one on a 1973 or later truck with a 205. Later trucks with aluminum tcases….yes.

Here is my stock ’78 K20 wrecker that I inherited when my dad passed away this summer. It doesn’t even have holes drilled into the side of 205 for a side mount or a support rod.

Larry,
A little input for you. I had a 1985 (or maybe it was 86) k30 SRW. the drive-train was 6.2 diesel/th400/np205 slip yoke. I never thought there were any 205's put in anything but crew cabs till I had this truck. It was not purchased from a normal dealership but from a medium duty dealership c4500's and up. I did not buy it new but all the documentation was still in the truck when I purchased it used, and the dealership is still in business. It seems that if you ordered a PTO option the np205 t-case is the case that would be put int it. Np208 did not have a pto option. Anyways, this truck with the np205 had the rod similar to the np208 running from the t-case to the bellhousing like you described. I have also heard of this rod referred to on the coloradock5 sight as well, so I am sure they exist for the np205. I bet they are elusive as big foot though.

PS What a great build, I really enjoy this thread I will be doing a nv4500 on my r30 crew cab soon, thanks for the inspiration!!

Larry,
here is a link to a place that specializes in the sale of older classic trucks. The picture is of a 86k30 srw just similar to the one I had, if you can zoom it in you can see that it has a rod bolted on the t-case just as I described in my previous post.

All K30’s came with 205’s (and Dana 60 front axles) regardless of engines so that isn’t that odd. The rod is a surprise though as I have not seen one on a 205. If I could find one I would use it…..that is if it would fit. Getting pretty tight under there. Seems these trucks have worked fine for over 30 years without a rod so I am sure they will continue on just fine.

i dont want to start show and tell, but my 89 v3500 has the th400/205 and it has the rod from the side of the 205 to bellhousing flange also
