Jost 5th Wheel Fit Holland Base?

This isn't going to help you a ton with your specific application but I do know that Jost makes certain plates to fit on certain Holland bases, any dealership should be able to tell you if there is compatibility I would think.

 

I put a new Jost on my old Holland base couple years back but I can't tell you model # of either one..

 

Go to their website and go to contact information. Fill out the form and they will call you. They called me back the other day in about 5 minutes.

 

I too have a 2004 WS with the Simplex plate. I spoke with both Holland and Jost at MATs last March and they told me that they will not interchange. Infact, since Simplex sold out they do not even make rebuild kits anymore for them. Mine is pretty worn out, so i will be switching to a Holland no-lube setup soon and just going to a stationary mount and ditching my slider. About $1,100 total for everything..... I know it's not the news you wanted, but that's what us Star Car guys have to get used to

 

Probably be cheapest to just get a new holland plate if nothing else will interchange.

Did Santa give you the necessities to slap on the turbine?

 

I have a Simplex-Lite 5th wheel. After making calls to Holland and Western Star, one of their guys called me back and gave me an interchange for a Holland top plate. he said it will mount to our current Simplex legs we have. He said the WS dealer should have this already in their system as a crossover plate, but the 3 places I went told me they didn't. i checked at the WS dealer in Abilene, TX and sure enough it had a crossover # for it and it matched what the guy from Holland told me. It is a Simplex II SE top plate, the only one they are still making I guess...... Hope it helps...
