What is this bracket for? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

WORNBRAKES · 05-17-2007, 01:47 PM

I have seen this on the 2 1970 4x4's that I have had. Nothing was attached to it so I am wondering what it is for. It is located on the passenger side just behind the tranny cross member. Thanks in advance for any and all help.

Chris27 · 05-17-2007, 02:07 PM

On my 72 K5 the transfer case (NP205) bolts to that braket.

**kwmech** · 05-17-2007, 02:26 PM

exactly--supposed to help keep the t-case from breaking the back of the transmision case when in low range---theoretically

WORNBRAKES · 05-17-2007, 03:00 PM

Is it for a 205 only or will it fit the 203 and 208?
Thanks

bowtier · 05-17-2007, 03:00 PM

Helluva spring pack on that thing!

I don't know about the 203s or 208s but the trucks that had Rockwell's have them too

Blazer1970 · 05-17-2007, 05:09 PM

The 208 definitely did not use the frame bracket. Some 203s (early models) may have.

I was shocked to see it myself. It was fun to remove as well. I had to put my large jack stands on cynder blocks just to reach the frame.

Thanks for all the great info.

The stickshift trucks had them too, at least mine did

1969k10stepside · 05-18-2007, 09:25 AM

So did my two 4wds that originally had 4spds

1969k10stepside · 05-18-2007, 11:35 AM

I just peeked under my 79 K10 and it didnt have that bracket.It has a NP203

babyJay · 05-18-2007, 11:43 AM

my 79 K20 doesn't have it - 203 TC, neither does my 85 K10 - 208 TC

Are you sure that's a K5 frame?

RANDY COX · 05-18-2007, 07:53 PM

I was thinking all the 4x4's had them my burb has it.

The truck in the pic is a 70 K10 frame. It was a manual trany truck. No engine, tranny or t-case come with it.
Here is a pic of my K5 with a 203. Looks like it could mount right to the t-case.

BLAZERMAN · 05-19-2007, 06:44 PM

73 and up 4x4s with 203s and 208s didnt use that bracket but they did use a heavy rod that bolted to the same 2 holes in the transfer case and it ran up to the transmission to block bolt right above the starter. These were usually left off whenever a transmission or motor was swapped out, it was a real pain to get to that bolt with this brace in place. This bracket worked in conjunction with two more strut rods that went from under the motor mounts to the heavy cast transmission pan on automatic trucks.

msgross · 05-19-2007, 09:12 PM

my 68 K-10 manual with a rockwell T/C has that bracket. T/C bolted to one part and the other to the frame. I just bought new poly bushings for it...

Yep,my 79 K10 has them rods.The tranny and t-case were removed and rebuilt before I owned it,I wonder how the previous owner liked dealing with them rods and bolting the t-case back to it.

eedgell · 05-19-2007, 10:34 PM

My 71 k10 4 speed 205 has this bracket, but my 79 k20 4 speed 205 does not. In fact the mounting surface on the 79 205 doesnt even have holes tapped in the case, just a smooth machined surface where the mounting holes would be.

3/4tonterror · 05-20-2007, 12:33 PM

i have that same bracket on my 70 with a rockwell t-case.
