Oil pan bracket dimension

I have noticed one of the pan brackets is bent in slightly. I want to fix this
before I start assembling engine
Where can I go to get the center to center distance to straighten it, or if
someone could give it to me I would appreciate it.
No frame available to measure.
Thank You
John

The arms are parallel to the frame. I wouldnt be too concerned. Recently went thru this. Once the hogs head is set, its real easy to fine tune the ear location with a 3' crow bar. Do check the ears for any hint of crack before installing the pan.

I would be concerned about the overall straightness of the pan? If an arm got bent? Did any other area get tweaked a bit? Everyone knows that a proper pan jig is the best to to check everything! However, a three foot machine straight edge and VERY careful measuring crisscross and side to side as well as front to beck, can determine if the pan is straight enough.
While hole placement is actually center to center, for comparative purposes, appropriate edge to edge is more accurate.
Frame width is 23 inches outside to outside, rails are an inch and a half wide each. Pan bolt holes are centered in the frame rails (3/4 inch from each edge), so quick math says the pan mounting bolts are 21 1/2 inches apart. Pan arms when everything is straight and square should appear to be straight up and down relative to the pan, and roughly parallel to each other.

Thank you for the center to center dimension.
One bracket is bent in 1/2" in. Looks like a little heat will
fix.
Did a check on the pan for level and twist by placing on
Vertical mill using DRO.
Every thing else looks good.
Thanks

NO HEAT. Use a pry bar or big pipe wrench with the H/H mounted to not bend the pan Or still mounted on your mill.
The blue wrench is rarely the answer IMHO.

If your pan is as flat and true as indicated, I'd be at variance with not using heat. Bending the arm cold will require really tying down the pan if there are not to be stresses added while bending. Heat will allow the arm to be shifted with far less stress on the actual pan. Either way, the pan should be checked again after the correction.
