transmission bracket measurements

i'm building a custom bracket off of the original m715 transmission brackets that are welded to the frame. my truck isn't with me, and i'd like to verify i have the right measurements before i show up with a piece of cut & drilled plate! can anybody grab them? i only need the measurements for the bottom 4 holes.


what i have is something like:
"O" = bolt hole

O <-3-1/16"-> O <------21-5/8"------> O <-3-1/16"-> O

Bolts start 21-5/8" on center, and are spaced 3-1/16" on each side.



thanks
