Looking for frame specs on 42 style big twin frame (de-chopperize)

[mdimages]

In the process now of "de-chopperizing" a 42 frame. This being said, some will go back to spec and others will not due to part availability and justifying price. I will be putting a Panhead back in it so some massaging will need to be done. I just want to get rid of the old modifications and bring it back to my spec. Here is what i have done so far.

Looking for some measurements if anyone has time to spec and help. again in wont go back 100% stock, i just want it to work with what im doing with the bike.
thanks Matt
