Top knobs for heater and ac unit

[fsalazar8187]

Hello everyone .
Two of my knobs have broken off on the top and I was curious what are the correct knob replacements the blue ones they sell online ?
I’ve seen online the one nearest the drivers side illuminates blue , however the one to the right is a different color . Can you guys tell me which color is the correct one for the top left and top right . 
I’ve included a picture .
Thanks in advance everyone!

Lots discussed here on how to replace the heater control levers. The original top right control was gray. Don’t forget to replace the bulb in there also.

Blue is top left, gray is top right.
You will want to replace all 4 levers at the same time. It is a big job that requires disassembling most of the dash. There are 2 bulbs, one left and one right.

Thanks everyone for the advice . I already have the dash out right now . What kind of bulbs do I need to purchase for the replacement ? I placed a order for the levers on authentic classics website
