Leaf spring hanger dimensions

[Cuda416]

Folks I am drawing up a set of dollies for my car (70 Cuda) and trying to find the bolt pattern dimensions for front of the leaf spring hangers.
I'd do a simple measurement but can't get under the car right now to do it. If someone has that info, I'd appreciate it.

Thanks

I don't have one handy to measure but the 2 top bolts are closer together than the bottom holes
