1969 Dodge Dart backspacing

CluelessMopar said
Hey guys, I have a 1969 Dart that I've converted to big bolt pattern with front disc brakes and rear drums. I was looking at Bassett D-hole wheels to put on my Dart but was concerned that I may not have enough backspace for the front fenders.

Anyone know if I would have any issues with 15x7 with 3.75 backspace for the fenders?

Bassett Wheels 57RF375: Black DOT D-Hole Wheel Size: 15" x 7" - JEGS High Performance

Consequently is this all too little backspace to use in the rear? I have a 8 3/4

here are pictures of our 70 dart with 15x7 rims that have 4 1/2" backspace. tires are 225/60-15. to me 3.75 is not enough,, if i did it again i'd go 4 3/4 backspace.

car has 73-up big bolt disc brakes up front and an abody 8 3/4 rear with dr diff large bolt axles and 11" drum brakes.
