Old man can't remember wheel specs

[SNKBITE]

I seem to have CRS (can't remember $hit) this morning.
I have finally located an aftermarket wheel that I like, that is
made in a 17 x 9.5 with 5 on 4.5 bolt pattern. However, I can't
remember what back spacing our wheels have. Can someone
please post it for me.
Thank you in advance for your help....

it seems to change depending on the width of the wheel, so keep that in mind. specs from afswheels website:

SIZE AND SPECIFICATIONS: We have combined two sizes on this set.

2 - 17" x 9" (+26mm, 6.11" backspace)
2 - 17" x 10.5" (+27mm, 6.9" backspace).
They are 5-lug (5 on 4.5).

These wheels will fit the 1994-2003 Ford Mustang.

We offer the replica 2003 Cobra style wheels with a Machined face/Silver cutout (like the OEM wheels), Chrome and Highly Polished Aluminum finishes. Please select your finish below. The price is for a SET of four rims with the AFS '03 Cobra center caps.
