    Ok, I get the NP203 back in and mount it up to the tranny. It takes a while but I found that using my motorcycle lift with a square of plywood cut to fit the lift works like a charm. I get it all mounted up and I'm thinking, man this thing is absurdly heavy. I can't believe that it is supposed to stay put with only the mounting bolts into the tranny/TC mount keeping it up. So, I look on the passenger side and sure enough I see two tapped holes in the case. I look over to the frame and see holes that seem to line up in the same area. I run and take a peek in the shop manual and sure enough there is a mounting bracket that goes to the frame from the passenger side of the TC. Anybody have an extra one of these laying about that has done a doubler? I'm thinking my only option might be pick n' pull because the dealer just laughed when I called the Part Dept. Seems I have half the bracket there but who knows where the other half went. My other Blazer didn't have this bracket attached either. Here is a pic of the bracket from the manual:

    I've never seen one with it, mines gone too, so is my brotherinlaws and a friend of mine, I wonder if they just didn't put them on some or if all the PO's in the world yanked em all, I found the 2 pieces of metal at a 4x4 shop and they wanted 65 bucks so I passed on that rape scene.... /forums/images/graemlins/eek.gif Fawkers.... /forums/images/graemlins/rotfl.gif /forums/images/graemlins/rotfl.gifI'm switching to a 205 anyhow, if you find them I have the poly bushings still in the package I'll sell you cheap.... /forums/images/graemlins/deal.gif

    If You can't find one, it's simple to make one out of two piece's of say 3x3 angle iron. Mark the hole's in both T-Case, and the frame rail, drill em out to size, bolt them in, then mark two more hole's where the two sit on one another, remove and drill two more hole's to join them together. The bolt size's, I beleive Mine are 5/8 in the T-Case, and 5/8 for the frame rail's.

    It looks like from the picture that it was a rather complicated setup with rubber bushings to handle the movement. I may be interested, let me see if I can get my hands on the stock ones. If not, I may go with the angle iron setup as suggested.

    Just "sandwich" three piece's of heavy rubber, or bushing's, one on top of the stack, and one in the center of the stack, and one on the bottom. To get that "body by Fischer" ride, and little vibration.

    Now there's an idea. I think ChevyFumes wants to unload his though... How much are they CF and where in the world did you get them? Does Energy make them or DayStar? I may have to drink and think on this one.... I do have some leftover rubber bushings from the original body mounts that I'm replacing with DayStar polyurethane ones...

    I think they are energy's and they are buryed out at the shop, so if you wanna make an offer let me know...They're just 4 round bushings if you wanna find them on the ES site to get an idea of price... /forums/images/graemlins/thumb.gif

    I did. They are called Transfer Case Torque Mounts by Energy Suspension and they are about $17. You sure it's worth it to ship them? You know anyone coming up to the SF bay area anytime soon?

    Seen that on Stick shift 205s but I have never found one on a 203. My bet is if they ever were on a 203 it was on the 74's with the stick shift. My 75 never had one and the holes are blocked on the 79 I had by the brace that runs from those same mounting bolts up to the bell housing.

    GM beefed up the TH350 in the mid 70's to deal with the weight. That's what is comonly known as the "K" case TH350 because it had a K on the side dnoting it was a 4x4 version.

    My concern with adding a 4th mount is acutally making it easier to bust the bel housing when the truck is flexed out.

    I've got a K case sitting outside but it needs a rebuild, but the TH350 that is in this one is a regular one. The frame already has the smaller of the L-shaped brackets, it's just missing the larger one with the bushings. I'd like to put it back on if I can. On the Blazer I'm building to keep, I plan on going with the doubler so I won't need the bracket I believe if I use the ORD setup. I may have to go pull one if I can find one at pick n' pull..

    My 1975 with TH350 / NP203 doesn't have the bracket or any hint of it ever being there.

    My other 74 has the smaller bracket with the crease in the middle, but it didn't have the rest of it. I wonder how many owners have taken it off to facilitate aftermarket exhaust, or other stuff in that area. Or maybe if your rig came with a K-case, they left it off...who knows.
