The 66 c-10 I have has a powerglide and the dipstick broke off, luckily not in the tube. I was going to buy a replacement but wanted to make sure that I got the right one.
Also is there was a way to replace the stick and tube with a better rig/elevation? Right now it's buried under plug wires and hard to refill which I have to add fluid every so often cause it leaks a good bit.
Heres the pic
