Master cylinder gasket needed

I have a 1977 Airstream motor home based on a Chevy P 30 chassis with all four wheel disc barkes. I need a master cylinder gasket. Its not the same gasket or master cylinder typically used on a rear drum set up, Its much larger. the gasket has Bendix 2228633 stamped on it. It measures 6 inches long by 4 inches wide. Very large master cylinder fluid tanks.  I can not find it at any big box auto parts stores. Does anyone here have one or a source ?

Overdrive with a Doug Nash DNE 2 on my Airstream Argosy

I have an opportunity to pick up a Doug Nash overdrive unit for a good price. I can get a full rebuild kit for it as well. Since its used, I am considering it a rebuild able piece and expect to rebuild it before I install it. I have been considering a custom build OD transmission but, the availability of this unit is making me consider going this way. 

I have a 1977 Airstream Argosy 28. Fully restored with a 454 thats bored stroked, balanced and blueprinted to a 496. I also…

Anti sway bar bushings on a P 30 chassis Airstream Argosy

Ok, this one is probably an obvious one. I need new rear anti sway bar bushings. I am writing this one in hopes of helping others by bringing attention to all of you to check your rear sway bar. front one too. I will give credit here to my friend Greg Blue. Fireman and Airstream expert from southern Florida. 

I noticed my Airstream Argosy motor coach seems to sway to much in the butt. Side to side sway as in a top heavy feel. I just installed new Air springs in the front and…

Possible vapor lock or ??? 454 / 496 GM motor

I had an odd incident last night. I pulled my 1977 Airstream Argosy 454 / 496 GM powered coach out of storage. I ran it about 10 minutes before leaving and then drove about 25 miles and stopped for gas. I pumped about 22 gallons of regular gas into it. It sat maybe 20 more minutes running while I pumped the gas. Then, right after I pulled out, the motor shut down. I got it to restart and then as soon as I got through the intersection it shut down again. I could hit the key and it would…

Motorhome engine and generator not starting nothing, no headlights either

I suddenly have a no starting seeming dead battery situation. The engine, 454 and the generator have no starting power. The battery is fully charged. I also have no headlights or other exterior lights. As if the battery is disconnected. Here is what I noticed two days ago. I have a wire under the dash that has been tapped into. When I bumped against this wire, I could here something in the inverter panel click. As if a solenoid was clicking. I pulled the electrical tape off the wire and saw…

Electric Fuel pump conversion,,greatest thing

I have a nicely restored 77 Airstream Argosy Motor home. Its powered by what you might call a hoped up 454 GM motor. In my quest to move toward EFI (electronic fuel injection) I took the first step by replacing my mechanical fuel pump with an electric fuel pump. This was the best upgrade I have done so far. Instead of pumping the gas pedal to the point of not knowing if you are flooding the carb in an effort to prime your carb after sitting several days, Now, I simply turn the key on, listen…

Rotted wood repair that works

I recently began doing some much needed winterizing and noticed I had some wood that had rotted. This seems to be a common item I see people mention on their motor homes and seems to be somewhat common on the class C motor homes where water penetrates via a cab over window and gets into the wood frame structure. 

Since I had seen this issue previously and did some repairs, I wanted to look back at the repairs I did about 5 or 6 years ago and see how those areas held up. As it…

Custom 4 Speed OD trans build

Tonight I spoke with a custom build shop in Georgia about building a one off 4 speed OD transmission for my 77" Airstream Argosy 28 motor coach. It will be based on either a 700R4 or a 4L80E. I am torn between having a shop build it or building it myself. My target is a getting my 3200 RPM cruise down to 2200 RPM. And being back up and running by spring. Probably taking my last camping trip of the year this weekend before I take the AS down for the trans build and EFI/TBI conversion

EFI conversion for 454 GM motor. Anyone done one ?

I have purchased a Airstream Argosy with a 454 GM motor. I love the coach for its beauty and retro aircraft style. ( Im a pilot) but, to my point and question. I am looking for anyone who has done a conversion from a Carburetor to a throttle body EFI ( electronic fuel Injection) There are several manufactures that now make a drop in bolt on kits starting at around 2 grand.

The benefits include better fuel economy , easier starting and reliability. The long term benefit is an…
