68 Wanting to replace he vaccum system for the Wiper Door
I am putting in a big block with tall valve covers and will have to eliminate my vaccum system for the wiper door on my 68. Has anyone installed an electric actuator for this? I saw years ago a post where someone made a bracket and installed an actuator. Does anyone have plans to build this bracket?

Couple ways to do it. I used a linear actuator.

Thanks Thats exactly what I was looing for
So you went with the 2" mini actuator? What are the deminsions of the brackets? I want to make sure they will clear my tall valve covers.

There's a 4 piece scissor mechanism in the well. I removed that and connected the actuator directly to the lever on the rod.
The actuator is about 8" long. I clearanced the firewall and bracket so about half the actuator is inside the well.

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.

The vacuum canister bracket is slotted to raise it up some. I have plenty of room. On the other hand I have power brakes and had to cut and weld a clearance area for valve cover. I can remove this cover very easy.
Have some pics in My Garage if you want to look.

Do you have power brakes? What valve covers? I have Brodix RaceRite heads w/ tall Moroso valve covers and Felpro gaskets on my big block.
