Just ordered some American Racing VN501's in 17x7 for the front, and 17x8 for the rear, but the dealer said the 17x8's won't fit the rear of a 65. What say you guys? I have a 65/66 5 stud axle.

I have 16x8's on mine........ however, the old Dodgestang chart has many folks successfully using
a 17x8 on the rear. I have a bare "mock up" 17x8 with 4.5" BS which definitely fits fine..... and although
I don't have rubber on it I think it'll still fit just fine.

With an 8" wide wheel 4.5" of backspace is the minimum amount of backspace needed and closer to 5" will fit better.

They have 4.5 back spacing, so I think I will chance it. Just to be clear though, mine is a 65 i6, but with a 65/66 V8 axle, currently with drums, but may convert to disc. Does this change anything?

I have 17 x 8 TT2's all around with a 4.81" backspace. https://www.summitracing.com/parts/are-vn2157866 Thats 4 13/16" BS to us old farts. Tires are currently 225/45R/17 Bridgestone Poneza RE 71's. They rubbed slightly on the drivers rear that I fixed in a hurry with a very hard rubber mallet. Hope to fit 245/40/17 Bridgstones or bigger this winter all around. A fender roller, mallet, and heat gun will be required.

I've got the Scott Drake Magnum 500's on my 66. The rears are 17x8 with 4.75 backspacing. I'm running 245x45's on them with plenty of room. I could have went wider with more back spacing.

Same wheels as bender, but 235 45 17 on front and back. Stock suspension but probably sagging (original) no rubbing issues.

With 1.4" drop front spindles along with the SoT coil over front suspension and 1" lowering springs and 1' blocks in the rear I'm kinda in the weeds ride height wise. I think 5" is the ultimate backspace for a 65-66 Mustang as it would put the tie rod in occasional contact with the tire on the track while allowing room for fatter tires.

The wheel supplier are doing their best to put doubts in my head.

"Dear Roy,

It is the body shell that restricts the fitment the 65 does not have the flared arches that a 67 has. A 17x7 will fit and look good on a 65, a 17x8 you will need to flare the arches in order to fit them, it is definitely not a direct bolt on fitment, sorry.

We would rather be honest than burden you with grief trying to get them to fit.

Regards"
