Anyone have current availability? Pricing, location, suggestions etc?  For 1989.

Thanks. Jim

Wabco STC 2784    Multiple sources online including eBay. This is a larger accumulator, equivalent to the Hydac, .33liter vs the .25liter standard. Usually requires adding a washer or two under the mount for the strut tower brace.

The original GM part number = 25528382

That is a starting place when you search..... if the seller refers to that part number their accumulator will likely interchange.   I would demand they take it back if it does not fit.  

The original had metric threads........ some accumulators have US standard pipe threads,  as 2seater noted some of the replacements work fine but are dimensionally different. 

there is an advantage to a larger unit but there are limits.    Adding the washers is an easy fix.........if you wanted to modify the cross brace that would also be easy to do.  

I would get a cross brace off a Riviera and modify that... keeping my original cross brace.
