A727 Rebuild kits redux - Rebuild kits everywhere (62-70 vs 71+)
AlV, you had some images initially with this post for the valve body mods you made per the Transgo TF2 kit. I could not find them and the old links listed here do not work. If you could repost these images so we can see them, that would be great!
These are the ones I am looking for.

I am in the final stages of my own rebuild. This is for a Big Block 78 Power Wagon, where I have spared almost no expense with the collection of parts going into this thing. I over build everything, with the intention, "It Will Never Break". In mine, I have replaced anything that was suspect, and upgraded a lot of items.
Billet Steel direct drum with 6 alto clutchs and kolenes, 9 springs
Modified 618 front 5 pinion planetary with steel splines (my stock 4 spline unit had have the splines pounded flat. Spline should look like V but looked like \|)
Bolt in sprag
new pump gears. WARNING !! Just cuz it's a new set, doesn't mean their in spec clearance wise. I order a new set, and it had more clearance than the one I was replacing. found one local that was nice and tight.
TF2 Kit
Modified servo pistons in all. had to put the space for the steel pin with a billet piston in my lathe to get the snap ring lan to become visible on the other side. Fun stuff.
Anyway, the filing of the notch has me paused at the moment for the VB modification due to the lack of pictures in the Transgo late series instruction set. That's what I wanted to see what you had done.
I also fully rebuilt the NP203 full time 4x4 transfer case. My God there's a lot of needle bearing in that thing. over 230 ! Got the last spider gear cupped thrust washers in the country in it. Week of research on that one.. I love the research..
Anyway.... Hope to see your pictures.

Well I've done it... My first build is in the books. :) Thanks for all of your advice and help!
One last question regarding the accumulator Blocker rod... I'm wondering if I should, or should not use it with the transgo tf2 kit. What do you think?
