Below is a list of NHRA approved locking dipsticks.

Does anyone know any of the companies below that have a product that works well in a 69 Barracuda with a small block, 904 and a CSR carbon fiber transmission shield?

I have one of the Lokar locking dipsticks and I don't see how I can get it to work.
