I modified the stock tube. Cut the mounting bracket off. Fab a new bracket that has the mounting hole 90 degrees to the original. The new tab will now attach to the boss with the hole on the trans bell housing. It will be much easier to install and remove. You can also rotate it in the trans for the most clearance before you weld the tab. Go to the junkyard and get a GM trans dip stick. Remove the roll pins at the top to remove the locking mechanism. Trim your Mopar dipstick .050" on each side at the top so the GM locking mechanism slides over it. You may have to trim the length slightly so it registers correctly, make a trial fit. Drill 2 holes where the roll pins went through the Mopar stick. Attach the locking mechanism with 6/32 screws and a dab of locktite to the Mopar stick. $5 at the junkyard and 15 minutes work.
