Great question!   Mine has always been this way and mounted internally.  Maybe Frank can way in on how his is installed on his roadster?  Not sure on coupes and sedans. Also, doesn't block glass/view if mounted like mine, right or wrong.

Wiper motor and vacuum routing on my roadster.

It's certainly coming together!

I believe mine is a Trico, as it looks like Frank's.  It's vacuum operated and operates by pulling the lever out on the body.  The lever can also be used by hand to wipe manually.

Hey Chet, just a comment and side note to this conversation. I usually leave my spark advance all the way in when starting, and I believe the instruction book says to do so as well if I recall. I do realize that retarding the spark during startup should make it easier to start. Just have never done it that way.  Upgrading to the 00 cables a while back fixed my starting issues.

Chet, for what it's worth, my Plymouth has been running QS 10w-30 since the motor was rebuilt in the mid-80's.

Same as Frank...wood/shims.

Nice work Chet!

 Glad I could help! Happy New Year to you as well.

Hope these can help a little, again from my Roadster.  If you want pics of anything else, let me know.

I'll take some pics tomorrow or Saturday.

Don't have a tourer, but a roadster if that would help at all.

Seasons greetings from Florida!

Chet, really looking forward to your findings on this project.  Also, which part # for the shut off valve did you order?  Now you have me interested in working on my tank during the next couple months.

Thanks!

On a side note Chet, if you do add an electric fuel pump, you might want to consider a shut-off switch.  I re-wired mine so that it comes on when the ignition is turned on AND the fuel pump/shut-off switch is turned on as well.  I originally did this to avoid flooding when my car was hard to start, but it's also a safety switch to shut off the gas for whatever the reason.  For your purpose (if you added a fuel pump), being able to turn this on and off at the dash when you needed to prime your vacuum tank would make it easy.  If I ever decide to rebuild my tank, I will most likely keep the pump in place regardless.

See the attached photo...I just added an additional toggle switch under the dash that looks almost identical to the toggle switch for the dash lights.
