No i have not, but it looks pretty straight forward. I was not going to mount them over the brake lines, i was thinking of mounting them UNDER the brake lines.
Either way, the project is a no go, the block i was sold are too wide, the u-bolts are not long enough either. Plus, i dont think there will be enough clearance on the underside, it looks like a have about 5in between the axle and the bump stop, pretty sure if i hit a good bump, the axle will hit the stop.
rather than lowering blocks on stock ORIGINAL springs, im going to go with these: speedway lowering springs
and use the factory u bolts, also i will either clean or get new shackles and hardware.
opinions? thanks for all the quick help!
