cruise control amplifier-part available?

[kelpforest]

Hello - My ole 94 Eddie Bauer Exploder has over 242K miles and runs like it was almost new. The cruise control stopped working so I've replaced the servo, speedometer cable and transmission interface but it still is not coming on. Also checked all the steering wheel switches and they are good. Which leaves the cruise control amplifier behind the glove box. Ford part number F37Z-90843-A - can't find anyone who has one for sale or even lists the part. The manual says to use a known good one to troubleshoot and that's why I'm looking for one. Is the junkyard the only option? Help?
Thanks

Got it - eBay $30 --- a "D" vs a "0" can make all the difference in the world..thank you!!
