I have done some research but got different results. Is it correct that the ;72 Demon have a bolt pattern of 5x4 or is it 5x4.25? Thank you for your help.

 

Everything I've found is 5x4.

 

Awesome, thank you. I am trying to find some good looking 14x8 or 15x8 (at least) wheels for it.

 

Never mind. Found something.

 

LBC = 4-1/2" for this era.
SBC = 4". .
Not standard for year I believe, but the possibility exists for Left Hand Threaded Studs on drivers side. Check for a letter "L" stamped in end of stud.


Search for charts or image on the net explaining how to measure wheel stud or bolt circles.

 

Yeah, I dont have the car at this house right now. I found 14x8 and 15x8 but I cant find any tires wider than 225 for 14 rims. Any tip? There is a rally style wheel on Summit but 14x8 but I cant find fat tires for it.

Also having trouble finding a tire. Im looking for something 275 or 285 in the rear.

 

Many folks have swapped out the SBC for LBC just for wheel options on these A bodies. You really need to know exactly what you have.
You might search http://www.forabodiesonly.com/mopar/...play.php?f=102 for wheels and tires.
If you go with 15" on the rear, these along with others were just on sale recently. Still a decent deal...................

What parts would I need to change for that? I was thinking about that too.

 

Your vehicle is different than mine most likely.
My '69 has had the 8-3/4" rear axles drilled for the 4-1/2" screw in studs and the stock 10" drums drilled to match. The old 7/16" axle stud holes were filled. Most don't recommend this approach today though.


I replaced my standard SBC '69 front drum setup with '74 Dart LBC manual disc brakes and master cylinder. Swapped out everything, upper control arm to the lower control as an assembly.


An excellent option and resource ...............

I found a good combo today.

In 15x8 and 275/60-15 or
in 15x9 and 295/60-15 although I could only find semi slicks in that size
