Booster and MC interchange

[MIHELA]

Does anyone know if the NBS MC or brake booster interchange with the OBS stuff? I think I need to replace both. The NBS booster is less than half the price from GM. I also like the reservoir design on the NBS.

The 06 booster has a 9 cm square bolt pattern on the firewall. The pushrod is 6 inches long, the body is 6 inches thick and the distance between the master cylinder mounting bolts is 4 inches. Does anyone have an OBS booster to measure?

I also wanted to clarify that this is a vacuum setup.

i relize the diesel is hydro but everything mounting and the pin should be all the same.

I have all my brake stuff off lying around. What part do you want measured? It's all from a 95.

 

[MIHELA]

Pushrod length, the size of the firewall bolt pattern and the distance between the MC mounting bolts.

I measured the best I could with a tape measure. The push rod is 7 3/4 inches from tip to the mounting surface of the booster. The bolt pattern of the booster to firewall is 3 1/2 top to bottom bolt and 3 3/8 side to side. The bolt pattern isn't square. I tried to get a cross measure but couldn't get that one. The MC mounting bolts are 3 3/8 apart. These measurements are the best I can do with what I have.

Rockauto has the booster for an OBS at $85 the NBS cost $125.
