I am currently installing my driver side fender, The fender is aftermarket but I cant figure out how to get the gap between the door and fender. Need help asap please.

Never looked at a B-body fender bolts but usually you use shims. Or you can shim the door to the fender.

There are shims to use at the body bolt points. You will have to experiment with the thickness.
