lowe's and home depot both sell vinyl tubing of various
sizes and whatever length you want.

but also, while you're in there, clean and regrease
your windshield wiper linkage and wiper arm shafts ...
to do the shafts, you'll need to remove the wiper arms
(outside), then remove the nut that holds the shaft to
those taperd black cone-thingies (that touch the body
metal). then the shaft can/will fall back into the dash
... but lucky you, you've already removed the dash so
you can easily get to the shaft and clean it and
regrease it and push it back out so a helper can grasp
it til you get out there to put the cone-thingie and
the nut and washer back on. :)

good luck!
