Thanks Jack!
Bill Taylor sent me a copy of your excellent article with the illustration of
where the drain holes should be drilled. It's exactly what I need, and the
illustration adds nicely compliments your description below. I already have
drain holes in the horseshoe, but wanted to verify that I have the appropriate
(number & size) drain holes in the lower frame rails too.
Thanks!
Garth

There's no tightly defined place to drill the drain holes. Starting from the
bellhousing area, drill three (or more) 1/2" dia holes, more-or-less equally
spaced along the lower rear frame rails. Also drill a 3/8" hole in the lowest
possible part of each 'horseshoe' shaped rear a-arm mount where its welded onto
the inner fender panel supports. This means four 3/8" holes & six 1/2" holes).
Be prepared for a small cascade of talcum powder dust and maybe mud or water
from each hole as you break through.
The lower frame rails have many 'doublers' welded into them; try not to pick
those areas for drilling 'cause the hole's entrance into the inside of such a
thick spot will be raised up so water might not completely drain, and because
its really difficult to drill these holes with a hand drill anyway; thicker
material just makes it worse. Deburr the outside of each hole for neatness, and
go for a drive; you'll leave a contrail of brown dust behind you for a few
minutes. Then you can touch up each drilled hole with rustproof paint. On cars I
have to work on, I first stick a flexible magnet in thru the big oval holes in
the frame rail tops. I'm amazed at what I pull or tease out of some Pantera's
rails! Bolts, nuts, broken spark plugs, big rocks... you name it... Good luck- J
