It's a street ride so no biggie. I had a feeling it would be slim chance. :)

Now, I'm just curious. What are the chances that my 73, f100 explorer, long bed,with a 360 ci; is a limited slip rear end? I'll get the number off the door tomorrow. :scratch:

I found the valve I need on Mac's auto website. Dual diaphragm shift moderator valve for 73-76. F100. Let's hope it fits!

Oh boy. Then perhaps I'll pull the modulator and take it in and try to match it up. I think different ford vehicles' transmissions had them in 73. I could also try to find out what tran I have on my hands.

I believe it's called a dual diaphragm modulator. What now? Perhaps the tranny is not original.

OK I found the modular vacuum valve. Very accessible. I checked the vacuum hose and it was full of liquid. So valve appears shot. The hose was old and weak also,so I'll change that too.There is a type of round ledge around the valve that has another hose coming from it. It runs parallel...

No hot rod here. Just which ever shifts calmly and smoothly. OR which ever one the store has when I get there.

Thanks for the heads up. could you tell me how I can change it? Is there a diagram and or instructions here on the site? I'd love to do it myself if it's not too hard. After the heater core I feel I can do anything on this truck.

Hi folks. I've only had the truck two weeks and I spent most of that time just getting it ready to use as a daily driver. (new heater core, welding floor boards, etc) Yesterday I took it on a long drive and it performed excellently- better then expected. But there was one thing that...

Vacuum valve? I only have two hoses one in and one out. Do I need a vacuum valve? So the ball valve will be set up in line and before the water goes into the core. It then reroutes it back towards the water pump?

Good to know. The truck looks pretty good right now. Not too much I really need. I might save for the plastic/rubber looking cab floor cover. I'll go see what Dennis has to offer too.

Wow! Thanks for the tip about LMC Truck It's like looking through the "sears wish book" at christmas time. (its a baby boomer thing)

So looking at the diagram: Without the A/C unit all I need is two hoses? One in and one out. Correct?

SWEEEEET! Ask and you shall receive. Thank you.

That 1973 pick/up is a f100 with a 360 that used to have dealer installed A/C that has been removed. Sorry for the lack of info.

It's was the very top of the defrost ducts that I reconstructed using the cardboard and duct tape. The bottom part was fine because , as you mentioned, it is of a sturdier plastic. The whole thing is now reinstalled. Thank you for the reply. I was pressed for time and decided to customize...

Hi all. I have a 1973 pickup with a 360. The truck had a dealer installed A/C unit that I have removed. I installed the new heater core, made my own defrosted ducts from duct tape card board and the remains of my old ducts, hooked up the heater blower and It all works. One last thing to do-...

Thanks!I took the old one out of the dash, It was all brittle and crumbling. I took some cardboard and duc tape and reconstructed it. I was able to use three of the original attachment holes with the clamps and recreated the fourth. Once completed,I put it back in. I figure the real old...

Hi all. My teenage daughter just bought a very nice 1973 ford f100! As nice as it is , it's still almost 40 years old. It has some rough spots. Of course, as her dad, it falls on me to make it a fun and safe vehicle for her to drive. I just put in a new heater core and the project has all come...
