I have a set of rally wheels being offered to me, 15x8 and 15x10. Does anyone know if the 10" rims will fit the rear ok?

Check the back spacing against your current rims.

The stock 15X8 Rallys had about a zero offset, so the 15X10s would need about a two inch negative offset or about a four inch backspacing. If they fit, they will definitely stick out past the body.
EDIT: I meant the 15X10s as now edited.

I have the stock 15 x 8 ralley wheels that I got from Ecklers. No clearance probs, and tires are still inside the wheel wells.

These are pretty wide, and look great. Still in the wheel well.
Cooper Cobra Gt Radials, P265/50 R15 Rear, on the 8" ralleys.
I don't have a photo with these wheels and tires on my Vette.
Oh, wait........yes, i do. I'll have to find them in my files, and will post the pics when I get home after work.
Gotta go right now.

This is the only one I found.

Not very good, I'll go ahead and take some pics and post them in the next couple of days.
A full 10" of rubber on the ground.

What is the backspacing/offset of the 15x8 stock rallys?

If memory serves me, it's about 4"/0". I've got a set under the deck but there's about 4" of snow out there. If you need an actual measurement, let me know and when it warms up, will check. Or maybe someone else has the info.

C3: I'm curious to know how much clearance you have to the parking cable bracket on the trailing arm.

I'll include that in the pics I take. I'll do the whole rearend, suspension and wheel clearance. I have the rear up in the air, so I shouldn't have any probs getting the pics. I'll try to get some measurements too.

Yup, a 215/60/15 on the right front.
265/50/15's on the rear.
All four are on 15 x 8 ralleys.

I've been doin' a little lookin' around, so far only 15 x 7 and 15 x 8 ralleys. If I run across any 10", I'll let cha know.

Sorry it took so long, but here are some pics of the rear wheels. 15 x 8 with 265 50's.
The rear wheels are about 6" off the ground, that's why they seem to be out of alignment.
