I was working on a 40 and stumbled on to this. I found that the gauges from a 60? To 78 F600 & 700 (cab overs also) and early econoline vans are a direct bolt in. The oil- temp-fuel gauges bolt in the 40 cluster with no modification and except the stock 40-gauge face standard or deluxe. These are 6volt gauges and the cluster has a small voltage drop on it. These big trucks are easy to find (truck wreckers) U-hall used them for years. While youre at it check out the steering column in the big trucks. Its got a nice thin mast (like early ford) with a turn switch that you can still get new from ford. Gauges may still be available also. If you have ever tryed to find temp senders for a 40 that work, you know why I did the swap.
