JD5303 rear SCV--standard equipment?

[HC-80]

I purchased my JD5303 new in the spring of 2007. While it was on the lot, I would almost swear that it had a set of rear SCVs. I had the dealer install a 512 FEL, and when it was delivered, there were no longer any SCVs on the rear. I chalked it up to my being mistaken, but I went to price what it would cost to have them added now, and it was quoted to be over $500. I also checked out the JD website and on the new model 5303, they are listed as standard.

My question is: Does anyone know if this was standard equipment on these tractors or am I mistaken about them having been there, and what recourse do I have at this point when talking to the dealer?

Sorry if this is not the correct place to post...
