41 chevy panel truck

[sumtercleaner]

The Nova is Leaf spring not coil. But I'm assuming the perch width will be diff and need new ones anyway. it's roughly 1/2" narrower than the oem rear. Diff wheels would be in the future anyways(not crazy about the ones on there and would like to go more 40's style so new wheels can be any bolt patter) What is the same on these as the pick ups? what is an easy way to change the front end to add disk and more modern suspension? Thanks
