Kerry, et al,

For your front access transmission dipstick, consider just modifying the
existing dipstick tube rather than replacing it. There's a bend in the
tube just above the FD. I drilled a 3/8" hole there, then distorted the
hole to a "warped oval" with a 3/8" rod. Into that hole I brazed a 3/8" x
12" tube, trimmed so it didn't extend but 1/32" or less into the dipstick
tube. A compression coupling and additional tubing extends the 12" to the
driver's side of the radiator.

With the minor interference inside the dipstick tube, I can still use the
OEM dipstick, with its top seal and vent (essential). For the extended
dipstick, I use a 1/8" steel cable, with the lower end brazed to eliminate
raveling and provide a markable/readable surface. I made a T-handle from
1/2" Lexan with a set screw to hold the cable at the proper calibrated
length. The "vertical" part of the T is drilled to fit over the 3/8"
tube. The small cable can share the dipstick tube with the flat original,
but if one wanted to, they could cut the original off short of the new tube.

It's worked for me for several years; your results may vary. :-)
