removing a gauge cluster

[james Langford]

Hello: I am in the process of converting from 6 volt to 12 volt. I bought a device from Vintage Auto Garage to attach to my gauges but I don't know how to get the instrument panel out of the dash. Working upside down in the dark recesses of the dash isn't an option for me. I barely have the confidence to do the conversion upright in good light. I am new at this but learning. The truck is a 1942 Ford 3/4 ton flathead 239 - 59AB.
I bought the multi gauge voltage reducer for $79 but living in Canada, the final cost was $190 with shipping.
I still have to work on the horn, wipers and heater. I hope it gets less expensive than the unit for the gauges. Thank you in advance for any advice.
