You're welcome! Back before I was born (I'm 36), my father was cutting parts off a car with an oxy/acetylene torch. He was underneath the car, supported by cinder blocks. He still tells me this story and I get chills. Randomly, he started to feel really strange, like something bad was about to happen to him. He turned off the torch, and quickly slid out from under the car. Seconds later the cinder blocks collapsed and the car (with no wheels on it) was laying with it's frame on the ground. That story was told to me at a young age and I'll never forget that cinder blocks used as cribbing nearly ceased my existence before I was even a twinkle in his eye.
Keep digging for parts, there has to be some out there!
Elsewhere a fellow told me at the 466 was the A version of the engine, 467, the B version, 468 the C model, and so on. As such, I ordered in a service manual covering the DT466B model and so I should have a complete set of manuals, minus the engine parts manual.
In other news, Thill Tractor came through for the throttle cable (which they can make for $250) and bleeder screws ($25 each). After calling all over to find an air horn valve, I finally called my local Fleet Pride, gave them the original part number for the air horn valve, and Fleet Pride quickly cross-referenced it all the way to the newest Bendix foot-operated airhorn valve for $52.00.
I also talked to ABC Caliper. They can rebuild my calipers as needed for $350 each. They have no rebuild kits available. Several places can rebuild my power clusters, but after talking to my local Fleet Pride, I think I'd let them take a look at them before sending the power clusters off on adventures in different states.
So now I'm waiting on bits to arrive so I can attempt to fix all the air leaks in the hopes the hydraulic side of the brakes isn't too roached. Stoked about the throttle cable as the existing cable is stiff enough were my lubing it may not bring it back and in order to lube the throttle cable I need to take it half off anyway, so I figure brand new is better—if for no other reason than new will be easier on my bum right knee.
I am having a hard time finding the stupid battery box latches, which I need three.
