The clear plastic cover panel for my gauge cluster has a good sized crack in it and I would like to replace it. I'm talking about the one in the very front that you can touch, I have no idea what it's called. I'm not sure which part number to order here, I'm thinking it's number 19.

Thoughts?

 

i think you mean #20 at this drawing:



78170-S2A-A01 LENS ASSY METER

be carefull to get correct version of this part - as there are a lot variations.

 

The very front clear seethru plastic cover is called the Visor. It's #18 on that picture above. It's #17 on the link you provided.

 

ok... visor or lens???
