1970 14ft mirrocraft deep v bench dimensions?

I have a 1970 14ft mirrocraft deep v the benches have been removed I plan to remake benches for it can anyone tell me what the lengths should be of the bench seats? thanks

Not sure if this any help, my '79 has 58 1/2 seats for the middle and rear, front seat at its widest is 55 and curves to a little smaller. Hope you can find some good brackets and are able to use the old holes.

Im trying to go original with as little fabrication as possible. But Im having trouble tracking down original brackets its looking like I will have to fabricate my own. Thanks for the bench lengths! the fella I got my hull from did a POS bass mod and took the original benches out Im sure the gunwales are bowed out some from original spec with the bench lengths to go off of it will be much easier to get them back to spec and fabricate new bench skins. again thank you!
