If your serious about switching your steering to the top of the knuckle. I have the steering links you need. They are set up for the GM TRE. 7/8x18TPI. When I was running my D30 I used these.
They are 1.25 DOM with some 1 inch .095 sleeved inside with some Poly Performance 7/8 x 18 TPI bungs welded on each end. One left and right per link.
You would need to get the TRE's and a reamer to ream the knuckles, one of the TRE's and your pitman arm.
I have about $100 into the set with the steel and bungs. I'll take $50 plus the ride.
