I understand about needing slack to avoid binding in the over center position.  I was just curious as to how you arrived at the 1.5 turns out.  Did you get that information from a service manual?   Did you experiment and come up with a specific value on your own?

 

I've rebuilt many boxes over the years for older Dodges and Ford trucks with the sagnaw steering boxes. Not my first rodeo... Doing seal kits in them are super easy, cheap and typically the steering box does not wear out just needs adjustments. There is no real book info of this slack adjustment, just over the years I found 1 to 1.5 turns out is about good for average slack. 

 

Like my OEM box Blue Top Steering said my box was like brand new yet and only needed one seal and out the door again in less than 1 hour was sold.

I have now driven the truck a few thousand miles, towed a large percentage of those miles, some of those towing miles were on 6% mountain grades, and the transmission just gets better and better. 

 

In the begining it was on the stiff side to shift and it took quite a bit of time to shift.  Make no mistake, it wasn't difficult, and didn't feel bad, just stiff and slow.  Now, the transmission is MUCH less stiff and I would say is 30% faster to shift.  It's no race transmission, but I would say things are actually better than when stock.  I'm very happy with how everything feels and functions.

I'm on the other fence with Valair Dual Disc. The clutch itself is rock solid. Throw out bearing is loud in every one of these I've installed. Works good throws fairly easy. Gotta be slow with 3rd gear mostly. 4th and 5th just a bit slow to throw too.
