I've been using these with success:

On my cars, with a 2004r with universal bellhousing, when bolting to a Chevy, this dipstick actually lets you just use a small bolt and go through the upper bolt hole that is not used when bolting to a Chevy block.
Make sure to follow the directions. For a 2004r you cut off a small amount of the tube to get the dipstick height correct. You want to make sure that when the dipstick tube is installed and the dipstick is pushed in and locked that the "full" mark is at the same level as the transmission pan gasket. Easiest way to tell is to install the tube with the pan off, put the dipstick in, and see where it is at.

Also, if you need a Chevy reference for transmission lines, you can use a 1987 Monte Carlo SS - they came with a 2004r and small block Chevy engine. You will probably have to modify the radiator end, but they will give you the proper bends all the way out to the front of the engine at least.
