    Default looking for REAR caliper bracket dimension... if anyone can check?..

    Hi,

    Hoping someone has their calipers/brackets laying around and can measure something for me..... looking on stock bracket/calipers...

    Hoping to get the distance as shown in the pic either on a BASE V6 rear caliper or a v8 gt caliper.... prefer the v6... but can use the gt size to see if I have the right one.... I just bought some v6 rear calipers and need to verify they are correct and not actually for the gt.....

    can someone measure from the center of the mouting hole to the center of the slider bolt..... either from bolt center to hole center... or as shown in attached pic.... this would help out a ton!!!... thx much!

    Huge thanks for doing that for us.....the community is richer for your efforts.

    Here's the dimension for the V6 VE/Pontiac G8 GT rear stock caliper.
    It looks like the V6 dimension is close enough to 1/2" less than the V8 dimension....on the mounting bracket (Item 7 on the drawing below).
