[Already Gone]

I can help you. The rallys came in 8's, 7's and 6 1/2. The 8's and 7's came on pickups and the 7's came on pickups with the lighter or base GVW Rating. as you said the 6 1/2's were mostly on vans. I've been buying and selling these rallys for years and although the 8 and 6 1/2 rims are plentiful the 7 inch are hard to find. I have a set on my 72 C10 and got lucky when I found them. The seller advertised them as 8 inch but didn't measure them properly and they turned out to be 7 inch. This is only pair of 7 inch I have ever found. If you are running a 235/75 15 tire like I am the 6 1/2's are a tad small and the 8 inch a tad big for that tire. Its real hard to tell the difference between a 6 1/2 and a 7 inch when a tire is mounted on the rim. The rims are stamped with the size on the backside lip but can be hard to see. The 7 inch are perfect for that tire. You may know this already but I'll say it in case someone doesn't know the rallys were never available on the 67-72 trucks and only came after 1973 on the square body trucks. The do look super on the 67-72's.
