66 cluster/gauges questions before reinstalling

[msg]

The cluster that I pulled from my 66 years back has been sitting around, and I thought before I just take it apart and do the sprucing I would ask if there is a way to check each gauge to see it if works properly before I put it all together. The speedometer from memory worked fine, but I dont remember how great each of the others were. I do recall the fuel gauge not behaving so good but that might have been the sending unit or wiring which will both be replaced with new.

So is there a way to test them?

Also, I plan to rig up that ebrake light I saw on this site a while back that replaces the tandem lock light. The over speed light though, I dont even know what thats for if I need to worry about it.

I wish I could afford the vacuum and tach replacement but those will have to wait.
