I agree with Tom on the vacuum wipers if you have a dual diaphragm fuel
pump. When I converted mine to electric I was not aware that Pontiac (I
have a GMC V8) had a dual pump. Since converting I've seen any number
of them for sale on that infamous auction site for $20-30, much less
expensive than the electric wiper motors. Also, the vacuum wipers are
infinitely adjustable for speed, not just high/low like the electrics.

I considered converting to electric wipers but found that the kits are
anything but foolproof, often don't fit without modification, interfere
with other stuff under the dash, and as Bill said, they are not cheap.
So, I found the wiper transmission pieces I needed anyway and in the
process located a NOS vacuum wiper motor for a reasonable price. I
installed the new stock pieces and with a new Carter double-action fuel
pump (the one with the vacuum pump) from NAPA, I found that the wipers
work
fine.
With my foot to the floor, pulling a hill at 0" manifold vacuum, the
wipers
still make about 70 beats per minute with enough power to wipe wet,
sloppy
snow. This is the stock setup with no extra vacuum tank. They are quiet,
which electric wipers are not, don't add an electrical load and are
infinitely adjustable eliminating the need for an extra intermittent
circuit if you want intermittent wipers.
I say save yourselves a lot of hassle and stick with the stock setup.
Most
of the reason people hate vacuum vipers is because the ones they have
are
worn out. Just replace your wiper motor with a NOS or reconditioned one
and
make sure the vacuum section on the fuel pump pulls sufficient vacuum
with
the line to the manifold disconnected. Mine holds about 12" of vacuum at
a
fast idle, less at 500RPM.
