How do I close the vents on my 1965 Mustang? - 1965 Ford Mustang

Doesn't matter. The forks inside the starter may be missing or broke off or bad spring in starter that pushes the gear out. Try new started. Starter may have to be shimmed to make contact with flywheel. Starter may be kicking out but not engaging flywheel.

Not exactly. The Mustang of that series had leaf springs and "overload" springs were usually a set with an extra leaf or two. Overload shocks were shock absorbers with an additional coil spring.
I don't think you could special order overload springs since the car was not designed to haul any extra weight like a truck or station wagon.

The hose is likely the differential vent hose. If you get under there and take a look around the rear end you will likely see where it was originally secured.

Remove rear seat and interior side panels. You'll see nuts on the posts for the trim pieces.

This sounds like too much fluid...

see if you can re-drill the hold down holes back 2"

latch may be worn out. If so, you need to replace it. Otherwise, make sure it is well lubricated and that the striker on the pillar is positioned correctly. Make sure that the hinge pins are not worn either or door will mis-align sometimes when closing. As for regualtor, first find one. Changing it is pretty much a take-out, put-in and adjust operation. If regulator is riveted in, drill rivets out and replace with pop rivets or nuts & bolts.

Hi pgarrity,hope this helps my friend good luck,this is simplified :)

To replace the window seal, you first have to remove the vent window assembly from the door. After it is removed, the nut and spring on the bottom of the window has to be removed. Then remove the glass and frame from the vent assembly frame. Then gently remove the rubber off of the frame and install the new one after you replace the top vent bar seals. Reverse the window removal procedures to reinstall the glass and frame. The top vent bar seals requires a special tool to remove and replace the rivets you get with the replacement seal. You need to replace the top vent bar seal before reinstalling the new vent window rubber. When I replaced my top vent seals, it was fairly easy with my removal/installation tool.
