Hi, guys.

My airplane is 59' C172 with notorious T-shape control column which prevents any try to center stack avionics from success.

I tried to put 2 KX-155s in the center area of sub-panel and want to put 2 VOR indicators just below KX-155s. Since KX-155s are above control column, there seems to be no problem with KX-155s. The issue is VOR indicators. It seems like I will only have about 4.5 inches of depth for my VOR indicators when my indicators(currently KI-208 and KI-209) have about 5.5 inches of depth. The only way for me to install these KI-208 and KI-209 seems like putting them 1 inch forward of the subpanel.

I noticed there are several many other VOR indicators which have shallower depth than KI-208/209. For example, KI-205 and other NARCO VOR indicator from my panel only seems to have 2.5 inches of depth which will be perfect for me as long as they work with my KX-155s. However, I'm not sure about compatibility of those indicators.

Please, anyone, tell me the SHALLOWEST VOR/LOC/(and GS) indicators which are compatible with KX-155. They don't have to be from King. However, depth will be the most important matter.

Thanks.

Jae.
