Transmission braces

[Magnuman]

I am looking for a picture (and the parts) of a part that braces the trany to the eng via the lower trany cover They will look like 2 ft roods with bolt holes on the ends.

Does anyone have a photo of what these look like, or better yet ones to sell?

They didn't come on first gen Blazers. AFAIK, they didn't appear until the NP203 was used in the Blazer. I think there was also only one on the passenger side of the transmission.

There was a brace used to connect the NP205 to the frame, but I don't know what years that was used.

I think your right that they didnt come on first gens, but there are two. I have them and they connect from plates that fit between the engine and the engine mount down to the trans. No, they definitly were not stock until after 72, because they only fit on the clam shaped engine mounts, not the square style that was stock through 72. I will try to take a photo tomorrow. I got mine at the junkyard. Not hard to find, just look for 73 through, what 87? automatic trans trucks.

Thanks for the response's. I would really appreciate a photo of the braces.

Don't you have to have the alum. flywheel cover w/ the 2 threaded bosses, this only bolts up to the 'K' case trans. Curious to see what these rods look like. Can these clam shell motor mounts bolt up to our engine towers?

[70rs/ss]

No, they would require the clam stle motor mount as well. They will work as this is a solution to putting a BBC in the 67-72 trucks without needing the OE mounts for 67-72 trucks. BTW using the Clamshell mounts on our year trucks 67-72 in 2wd or 4X4 applications, allows the use of headers and will clear them as well. Some of you will already know that, but wanted to share in case someone else didn't. Good luck on the hunt!

SOOOOO, let me try to put words in your mouth, and see If I understand you correctly....If I get the '73 and up engine towers and mounts, I should be good to go. Thanks for the help

If you can get the engine crossmember (73 and up)as well it is a bolt in deal, but the clamshells can be bolted to the 69-72 blazer crossmember I think, just drill the holes into the existing crossmember and bolt them down. I'd guess a wrecker would sell the whole crossmember cheap and the clamshells should be replaced (inner rubber bisket gets soft), an OE type clamshell can be had for $20 from the cheapy auto parts stores or a urethane bisket can be bought and inserted into the clamshell (opens like a clamsheel and the bisket drops in). LMK if I can help any more. In a 2wd the 73 and up mounts can be bolted to the 67-72 frames and used for a SBC or BBC install as well.

No, I think that is all the info I need for now, you have bin very helpful and informative. I'm going to go hang out on the '73 side and see if I can find the parts, looked before, but no help. I'm having a problem with my oil pan hitting the crossmember, so maybe I can kill 2 birds with 1 stone

I believe the 73 up set up would put the motor up a bit higher as the clamshells and the motor mount are quite a bit thicker than the 67-72 OE type mount for a 4X4. Do you have a local wrecking yard? I have seen tons of them around but never needed them? If for some wild chance you can't get a set up, LMK I can probably pick one up here and ship it for ya? LMK

Sure, we have couple of 'you pull it', just wanted to give the board members achance to make a buck

Aren't you coming up for surgery soon?

[70rs/ss]

Had it done 4 weeks ago or so. I can't "do" anything but sit at my desk and surf! My yard pulls the part so it wouldn't be a big deal, but if you can get one from a member that would help them out, just LMK.

I just pitched a set last Monday when I sent my pickup to the scrap yard...

That's my luck, a day late and a dollar short

[70rs/ss]

Ain't that the truth!! That darned Murphy and his law's!!

[Magnuman]

Mraley,

Did you get a chance to take the photos of those braces?

If I can't find them I will probably fabricate them.

Thanks.

The pieces between the block and motor mount is just a flat piece of steel around 1/4 to 3/16th thick. I can try to get a pic of the ones on my 90 Blazer this afternoon...

Sorry about the delay - covering for two other people at work is killing me. Anyway, I took the photos, not the best light but you can see what he is talking about. The only thing is I cannot get the photo to be less than 100 kb, which is what it says the limit to post on here is. I'm gonna try it anyway.

[myraley]

Cool, it worked. I had to shrink it to fit, sorry its not bigger. Anyway, that is the strut. The diamond shaped piece bolts directly to the engine (three bolts in a triangle) and then the metal clam shaped piece bolts to that. Here is a photo of that, if it will go through.

[myraley]

Cool, that worked too after I shrunk it. Ok, so that square shaped thing bolts to the engine, with the side you are seeing against the trans strut and engine. The other side is hollow and that is where the rubber or poly engine mount goes. This is all stock 73-86 stuff, and you can see in the Haynes manual from Chevy and GMC trucks 67-87 diagrams of this. The installation is described at the end of the automatic transmission section, and the engine section shows the engine mounting. NOTE: this will not work on 67-72 engine frames, they are completely different. This design is better, which is why I have these parts, so I can take out the stock engine mount from a 72 (which is u or cradle shaped) and install this design and mounts (much stronger, and will allow you to remove the oil pan without removing the engine. Hope this helps.

[jaros44sr]

Cool, thanks for your time and pics, finally I can see what they look like. Are both rods the same, right and left....search for these parts is on (not a wtb). Now, if they will only clear my 7 qt. oil pan, I'm good to go. Thanks for all the info. guys

[Magnuman]

Thanks for the photos. Now, I have to try and find them or have them fabricated.
