i just did an sas swap on my 85 blazer. ( solid axle swap ) and i need to know if there is a pitmen arm i can get that doesnt have the ball joint in it. or if a fullsize blazer arm will bolt tho the gear box on the 85.

 

when i did mine i used a astro vanbox and used the stock pitman arm. its a identical box but i think its reversed rotation though... so that will work but it doesnt have a drop. depending onhigh you went it might work. i have maybe 9-10 inches of lift and it works perfect with crossover steering. the drag link is straight. but you might have to ream out the hole depending on what tie rod ends you used. i used the ones off a k5 blazer and had to make the hole bigger... even easier if you go with heim joints
