Review on ProForm 66181 TH350 Locking Dipstick and Tube: Reliable and Convenient Transmission Solution by Gervan Mauldin

I used this to replace a broken capless dipstick from the 1970's on a Chevy pickup. All I needed was the probe itself, but I couldn't find one the right length so I bought it as a kit. However, the mounting tab is designed to attach to another flare bolt on my 350 V-8 that is higher up and very close to the firewall. Even after bending the tab, I still couldn't align the bracket hole with the bell body hole. I finally gave in and attached the pipe to the 3/8-16 bolt hole on the back of the cylinder head with a 3/4" wire clamp and 1/2" spacer. I can end up with a shorter stance. Also had to do a bit of rerouting with the new wiring I just installed. I can't check the bottom gasket for leaks until a few days later when I start the engine, but it looks like it's tight. On the top end, I like the locking feature, where snapping the lever "in the middle" stretches the rubber seal to fit snugly against the case.
