All,
Been following this thread as I Need to do mine also. Went out and took some pics last nite to see the differences. My shackles on the 4t6 are not the same as the 1/2 T as pics below show. I had a local spring shop make me the ubolts and will have them tighten up the spring curls. I made up new brake lines a couple of nites ago and got them mounted. I think I'm gonna take them back off and polish with brass wheel and clear coat. I played with a piece of scrap tubing and I liked the results. Thanks to all for support and help. Have a Merry Christmas and a Happy healthy New Year
Dan
