Need knowledge about customizing a chassis for my 46...

[BenjaminB]

Hello, I've got a 46 Chevrolet stylemaster that I'm in the process of turning into a hot rod. Right now I have a 9" ford rear end on the original leaf springs (just using them to get my measurements right), I already cut the front clip out about 7" from the firewall and now I'm trying to get the proper wheelbase length because I'm installing a 76 cameo sub-frame in it. I was wondering since i have both a new rear end and new front clip will i still need to have the original wheelbase of 116". The problem that I am running into is when doing my measurements I realized that the front wheels will be sitting about 3" forward in the front wheel wells then where the exact middle of the wheel well is.

Now if I were to just get the exact length on each side so the front wheels will sit exactly in the front wheel wells and attached it to my chassis that way, will it throw off my geometric s and such of my car or will it not really matter? Basically is it unadvised for me to turn the original 116" wheelbase into a 113" or 114" wheelbase to line up the wheels in the middle of the wells, even with the new rear and front?

I appreciate the help and apologize if I am confusing in my description of the situation.
