Mini tub Dart wheel sizes

I chopped a c body housing down to the stock width of 52 5/8 and moser 28" axles
I did my own doggie dish rims 15x10 and 7.5 backspace
Home made 15 x 10 with 5 on 4 1/2 b.c. and dog dish hubcaps.

I run 325/50/15 nitto drag radials.

Plus my rear disc brakes dapters which also moves the wheels out about 1/4"
Rear disc Brakes on 8 3/4

Ok enough tooting my own horn
I have heard it is harder to mount the wheels when there is lots of back spacing. Have you found that to be true with your setup? I want to keep the same front spacing with the steel wheels to keep it somewhat stock looking
