They don't carry the same one I bought any more. I went with the one with the greatest force. Typically they are slower, allowing the wipers to park before the door closes.

Default C3 wiper door 1972 with AC

I finished the install of the wiper door actuator. I used a 2" linear actuator I bought off Ebay for $40.00. I drilled and tapped the end of the aluminum rod for a 5/16 x 18 tpi rh thread to accept a threaded stud that screws into the long factory hex adjustment nut. I cut 2 aluminum angles from Lowes stock and bolted them to the factory bracket the vacuum motor was attached to. The factory rubber bellows even fits over the actuator. For now I am using a separate DPDT momentary contact switch to operate the door. I may add relays etc later to work off the wiper switch. I plan to try to hide more of the actuator in the firewall later on but this mounting is OK for now.

Looks somewhat familiar....
So you kept the scissor mechanism and rod? I removed all that and connected the actuator to the arm that comes off the pivot rod in the wiper well. It moved most of the actuator into the well, but probably doesn't make it work any better.
If you wire to the wiper switch with relays, just be sure the actuator is slow enough that the door wont close before the arms park.

Do you have a link (or model / part number) for that actuator?
This arrangement will probably be easier to fit for my application vs the power seat motors that lie against the firewall.
Thanks!

Here's the wiring-

And those wanted an actuator - here's some food for thought- a cable driven one- can use a longer cable-

Here's an inexpensive way to "slow" the actuator down- it's a simple adjustable timer circuit- I think I got it for about $10 shipped.

Wire in door closing and it will delay the closing from a couple of seconds to a couple of minutes. Can be negative or positive triggered.

Default here is the 2" actuator

Wow, 225lbs? Kinda overkill, but that price is great.
Btw, have you guys seen this? Kinda pricey.

WAY pricey! Wow.. And not even an attractive solution at that.
Must be all solid gold components inside

Yeah, I've been looking around and even though you could probably get away with a 25# or less rating, the speed is what you need to watch for.
The lower capacity units are like 1" a second while these 225# units are between 10mm - 12mm per second, which would help avoid any contact with the wiper arms.

If you Google the above wiper door kit manufacture web site (there is a site that shows the inside of the $1.300.00 kit). It looks like the actuator is uses is identical to the one I bought on Ebay for $40.00 . They just wrapped it up in a big ol' aluminum/steel box.
