I like the quality of the façtory GM engine oil and transmission dipsticks, but in their stock form, they are way too long. I wound up getting an oil dipstick and tube from a 1995 Chevy truck and chopping it down about 12 inches. I also used my tubing bender and bent the tube to the angle I wanted. In this shot, you can barely see the yellow handle. It's easy to access, but it's out of sight.
I really like the lockiñg transmission dipsticks, so I got one from the same '95 Chevy truck and chopped 11" inches out of it. I could have cut it down more, but I didn't want to make it hard to reach.
