    Trying to remember what the pinion angle to use with SS springs....I am wanting to believe it was like 5 degrees nose down...

    Got Solid aluminum front eye bushing going it also.....

    Dropping 7 1/4 inserting 8 3/4 hopefully this weekend if all the small parts get here.

        Nah, try 5

        The solid front eyes will stop a lot of the need for additional down angle. Missed that first time around.

          I set mine down 5 degrees down. I have SS springs and slide a links. Also Viking double adj shocks. Goes straight as an arrow and not a vibe at all. Kim

            Still waiting on a bunch of small parts...axles seals...housing studs...studs for axle ends...solid aluminum eye bushings....everything should be here on friday.....

            Using a stock length A body 8 3/4 that has been sitting in the shed for many years...came with ladder bar brackets and floater for the springs....used grinder to get rid of floater hardware....not sure I am going to cut the ladder bar brackets off yet...anyway....

            Have had these 002/003 springs for over 10 yrs....they had very short lives on a Dart and Duster. Got the 3 way CE rear shocks....all left over parts....
            It pays never to throw anything away...

            old 7 1/4 hanging by a couple of bolts...roll the old one out....roll the new one in...

              Dropped the 7 1/4 rear end this morning...complete rolled it out of the garage...maybe some one will steal it tonight....or might be heading for the recycle yard...
              Removed the rubber spring eye bushing on the SS springs...drill and air chisel made fast work of those....Hammered in the new solid aluminum bushing...a little wd40 helps..
              Got the spring perches welded onto the 8 3/4 housing.....gotta touch up the paint on the housing...and drill n tap for a drain plug...
              Paint front hangars...got them glass beaded this afternoon....
              Need to have this Duster able to roll again in couple of days as attention is going back to 71 Dart as heads will be back next weekend.

              LOL
              Your pic's allway make my eyes see something that is just not there.
              See that rubber mallet in the picture? erase the wooden handle from the picture.
              That's what i saw at first glance, thinking Why the HUGE BUMP Stop, on the SS Springs?............then i saw it was a rubber mallet :lol:Yeah i know :realcrazy: :)

              Enjoying reading this, but am a little confused.
              I know what pinion angle is.....
              Would you guys mind explaining 5 degrees down??
              I put SS Springs on my Demon and will have them bolted in as the stock ones came out.
              Is this good/bad?
              I assume the angled wedges would come into play if needed?
              Thanks all.

              Got the SS springs and rear housing in the car....replaced the axle seals....got the new bolts in the housing..CE shocks....

              I drilled the housing for a drain plug but could not find a 1/8 NPT tap to thread it. So tomorrow go pick one up.....get it tapped and plugged.

              Then third member and axles can go in....and I got the brake drums and backing plates left over from one of the other cars...

              Black paint...lol

                    Did not get the frame rails welded today....but got the fuel cell mount done....
                    my floor is a mess...need to clean it up before I set car back down on the jack stands to weld frames in.....but as I say...get something done everyday...

                    I only got another week or so until I have to abandon this project again for awhile....we have one more race on Jun 3...then down for the summer until Sept....
                    I will be working on the 71 Duster Mean Green Machine....gets a new Dana and 408 engine...
                    Never a Dull moment around here...LOL
