During the trash to go wheeling this weekend, i was screwing around with the cross memebers. I had one under the 203 adapter just to get it up. Now that I'll be installing a front driveshaft ( /forums/images/graemlins/rolleyes.gif ), i need to remove the 203 cross member and install on on the ORD adapter. I tried to bolt up the rear, but it looks like i'd need shims. there is about 3/4" gap between the frame the cross memebers front bolt holes. 1 1/8" between the frame and the rear ones. I know a few people are running doublers with just one cross memeber on the ORD adapter. anyone running dual cross members?
