Can't seem to get levers to go all the way to full on or full off in there slots on the control panel.Have installed all new cables and everything works freely when disconected.Is there some kind of adjustment other then 1/2" you get on cable mounting tab? Also when control box is fastened into dash it is pulled out of square to dash opening.Is there some kind of shim that goes between the controlls and the dash to keep it centered in the opening.The manuel shows nothing.

Assuming the under dash box levers are going to the full open/closes positions, then the levers should also follow... Check to see, maybe the box itself is binding...

As for the control centered in the dash... Its been a while, but I don't recall enough room to really be off-centered... As I recall, the lever assembly actually sticks through the dash opening, using that opening to center itself... If you mean not centered into and out of the dash opening, are the holes underneath slotted at all for adjustment?

I have had many 66 Chevelles, but my current one has a heater delete setup... Sorry...

I'm sure the levers on the box are opening and closing fully.Maybe the cable is not the right size?Its mostly the lower heat/defrost leaver thats giving me trouble.
By not centered I mean that when the bolts are tightened up it pulls the control box down at an angle so that the raised edge on the box does not project through the dash uniformly.Theres a slight projection through the dash on the bottom and a negitive projection on the top. Thanks Pat

Maybe the lower portion of the dash has been bent (where the controls screw to...). I have never seen a factory shim for this, but you could fab one up and nobody would know...

Cable length shouldn't matter, but the distance between the cable and the cable housing (at each end) might be causing the problem by limiting the cable travel...

I would disconnect the cables from the box, and see if the levers are then able to travel the full distance while only hooked to the levers... If they work like that, then try to move the box levers by hand to the extreme positions, and with the cables/levers already in the extreme position, see if the cable end and cable mount will both line up...

If you look at the terminating ends of your cables, on the heater box, you will see that the place where the screw that holds it in place is slotted.
these can be moved back and forth to adjust for the problem you have.

Pat, Check your heater controls for either bent arms or excessive wear. The original units were a weak point and suffer from wear and or distorted/ broken arms. If you had sticky heater doors or cables this puts alot of strain on the control unit. I had the same problem on mine.Replacement arms are available in steel. Check out aces web site, I thought I saw an article on rebuilding these units. Hope this helps.

Thanks to those who have responded.Installed the controll box last night with a shim between the unit and the dash to get it to sit proper in the dash opening.(still scratching my head as to why I needed to do that)Reguarding the cables I bent the levers on the heater box in such a way that I got full travel with the levers on the controll box.I think it may be as paterson said that something somewhere was bent.With nothing to compare it against I don't know for sure.Pat
