Setting up dipstick

I've had several D truck and B van pans, that I've modified, I think they all had a curved tube spot welded to the pass side of the pan. This tube guides the long dipstick into the deep part of the rear sump pans.
Thank you. I didn't know that. I may have the wrong dipstick after all. I'm going to try to find a Mopar performance dipstick assembly.
