I just thought I would let you guys know how it is going. Old 4" TC's are out (and for sale) New 7" eye to eye shackles are bolted in. Front axle chilling while i slowly drill out 16 rivets. I tried everyway mentioned on this site and this one works the best. about a rivet every five mins. The pilot hole is what takes all the time. I wonder if my 10" lift brakelines will be long enough. HMMMMMMMM time to set up front brakelines like the rear ones. Well back to work 8 rivets to go. Woo hoo.
