Just ordered up. eBay listing said "last one". Perhaps eminent room marketing ploy, if so worked for me. Besides I did prefer not swapping out throttle plate(s) if not forced to. I believe now you must also change out throttle butterflies to new plate(s). Am I misremembering that at one time this was not required?
There was a problem with some of the early plates sticking,they were stamped #199,plate stamped #226 corrected the problem,no need to change.
