That looks like the right part, but I couldn't say for sure.

I guess I'm not understanding what you want to know. Do you want to replace the valve with a stock replacement, or an adjustable aftermarket one?

I want to replace it with an aftermarket type of valve.

Sorry, I can't be of much help there, I thought you wanted a stock replacement.

If I wanted stock replacement parts where would I find them ??

stock - original specifications but not neccessarily manufacturer, will match original stock specifications for the vehicle.
aftermarket - higher capacity type items for more power, speed or strength

for this type of item and availability, I would assume stock is your only option...
