I'm putting my drivetrain all back together and I noticed something. I have an np203 and the only thing that keeps this in the truck is the one crossmember at the back of the transmission. Why isn't there another crossmember at the rear of the transfer case? All that holds this huge t case is the 8 bolt on the 203's face?
Heres what I'm talking about:

This crossmember is the only think that holds the np203 up? Am I maybe missing a second crossmember?
And in this picture you can see little one inch spacers between the frame and trans/t case crossmember. They were there when I bought this truck so I just put them back. Are these normal? Or could it have been an attempt at a transfer case lowering kit, even though the truck is not lifted.

You are right someone has tried to make a homemade drop kit.

Those spacers are not factory. And the cross member you have is the only one. There is none for the transfer case. I have seen some them with a piece of angle iron that bolts to the right side of the case and to the frame with rubber bushings between the frame and angle iron stock.

i have them spacers on my 94 4x2 but they are on top the frame don't actually do anything but make it so you can use a half inch longer bolt, i don't even think i seen a transfer case support on a 203 just on a 208 that was a bar that ran from the case to a bell housing bolt and lets say whoeven took the bolts out didn't see it eather so it kind of cracked the bell housing

I just took a 203 out of a '77 1/2t, and working on my '74. I also had those spacer under the nuts inside the frame on the '77. I'll check my '74 tonight. The '77 had only one crossmember under the trans, but the '74 has an extra side support brace connected to the side of the t-case and frame. I'll shoot a picture tonight if I get home in daylight.
Good luck.

The earlier trucks, 73, 74ish, came with a transfer case "L" bracket, but newer trucks are just like what you have there, as do I. One crossmember, under the back of the transmission, nothing holding the transfer case besides the bolts. Nice, huh?
As for the crossmember drop, that is what I have on my truck as well. Just 4 aluminum blocks. Skyjacker is who I got mine from.

so i can just leave those spacers? I do plan on lifting the truck so I guess I would have needed them eventually.
Heres a picture of everthing together:

To me it just looks weird, its just hanging there, but whatever thats how it was when I got it and I beat the crap out of that truck and the t case didn't go anywhere. I'll have to decide on if I should scrap those spacers or not, what are your opinions?
