I upgraded my panel a few months ago, I have an assortment of removed stuff.
Garmin 250XL with cards, tray and antenna $900
RC Allen attitude indicator $250
RC Allen DG, best one I ever flew behind, precession was very minimal $400
Bendix vacuum turn and bank $40
VSI 0-6000fpm $25
airspeed indicator $30

Also have the wet vacuum pump, suction gauge, regulator, oil separator etc...

I also removed a set of Atlee Dodge steps that clamp on the strut. They didn't fit my struts real well, so I wonder if they fit a 185 strut better?

Hi, Are the RC Allen instruments vacuum operated? Thanks, Chris

Yes

Do you have a part number or dimensions on the refueling steps? I may want them for my 182 if they would fit.

I measure the steps, they are 12.5" from the 90 degree where the bolts go. So, I am guessing they are for the struts that have a circumference of 13".
