The Willys is going to have a one-piece tilt front end. It will be opened/closed by two linear actuators. Although the actuators will keep the tilt front closed, I still wanted a secondary latching system to keep everything secure.
I decided on using a couple of motor operated suicide door latches as shown in the first photo. The units are fairly large and it took a while to find a place to mount them where they would fit and still allow the latch pin to protrude through the firewall.
I decided on putting them in the unused "horn" areas that protrude forward from the firewall. Although the fiberglass is fairly thick in these areas, I wanted to reinforce it for the through bolts that hold the latch to the body. I epoxied a piece of 1/4" plywood to the inside face of each horn and drilled the mounting holes and latch pin hole as shown in the second photo.
The last photo shows the latch fit up in position. The pin protruding down from the bottom of the latch is for a manual release knob.
The latch is only supported by the two mounting screws through the body at the front of the unit, and it needs to be supported at the rear also. The firewall frame that I made earlier will come in handy again as a rear support point.
First photo shows the wiper blade location when parked, and second photo shows wiper blades at maximum sweep. Coverage is not complete, but favors the drivers side. These wipers will only be used in case of rain, and otherwise stowed away. The posts will normally have a finished cover over them.
Last photo shows the entire assembly from the inside. The excess portion of the drive cable that extends out of the tubing to the right of the transmission gets cut off, and a cover plate is bolted over the exposed drive to finish everything up.
With some careful hand bending the aluminum tube between the wiper motor and first transmission was fit into place. The wood frame was cut out as needed to keep the tubing tucked away and not in the way of any interior finishing. Upon final assembly, the tubing will be epoxied into the cutouts in the wood frame to keep it from moving. The right wiper transmission was located and installed in the same manner.
Second and third pictures show the before/after wiper drive shaft and threaded post installation. Post and shaft were cut off according to instructions.
The aluminum tube needs to be flared at each end in order for it to seat correctly in the transmission housing.
The first photo shows how the tube flare sits into a groove in the drive cable housing and how the rotary motion of the motor is converted to the back-and-forth motion of the drive cable, just like a piston in a cylinder. Different holes in the disc will give different sweep angles of the wiper blades.
The second photo is a closeup of the wiper transmission with the backing plate removed. The tubing flare sits into a groove in the transmission halves and is locked into position when the halves are bolted together. Also seen is the drive cable meshing with the wiper drive gear. This whole assembly gets greased liberally so that the cable slides back and forth easily inside the tubing.
With the wiper arm located, the wiper transmission was mounted next. The Outlaw Willys body has a wood frame running around the interior portion of the windshield opening, and this would be a good place to mount the transmission.First photo shows 3/8" hole drilled straight through frame and body. I decided to inlet the wiper transmission into the wood frame so that it would be flush with face of the frame for a few reasons. First, the wood was thick enough to do without weakening it, the transmission would be better supported, and most importantly, there would be no bulge sticking out of the finished headliner.
Second photo shows the frame carved out after a few minutes work with a router.
The last photo shows the transmission installed flush with the wood frame.
