Re: 1947 Panel Truck Frame swap with ’88 k2500

Thanks Old57, I saw the pedal in your build and thought it looked beefier than other options, and at a good price.
I brought the Beast home last week, placed in a tent and began checking things out.
I moved the boxes of old parts out and started surveying things. I’ll make a list of what and when to do.
I finally heard back from the Radiator shop with an estimate so I’ll be getting the radiator soon. I’ll be able to test fit it myself. They will tack the brackets on, if it fits well, I’ll have them finish it. I took the driveshaft to get it extended 4 ½ inches. Progress continues.
I had refaced my speedometer, but discovered the high beam indicator lens was deteriorated. I found a refresh kit, so had to wait a week for that. After reassembly, the display would not read above 20MPH. I tore it apart again and discovered the spindle was independent of the speedcup. I glued the spindle and tried again. It took forever to get to top speed, and seemed to hang high before dropping. I tore into it again and found the speedcup binding. I removed the superglue, shimmed the speedcup and glued the spindle again, and again I didn’t get the orientation of the speedcup to stop correct. It didn’t rest firmly at 0. It was also binding again. I found that I could get just enough wiggle room to get clearance. I was able to loosen the screws of the speedcup assembly and spindle bracket and shift it enough to work. Once there was free movement, I looked at the stop tab. The speedcup tab was just past the stop tab, so I rotated it around and past the stop tab. I had to bend the stop tab up and then back to get the tab on the speedcup past. This put one revolution of tension on the spring. Now it didn’t read full scale, couldn’t overcome the spring tension. I tried to put it back and in the process of bending the stop tab, the tab broke off. I let the speedcup in it’s relaxed state, preset the spring by about 20 degrees, and glued a piece of wire as a stop. Upon reassembly, the old needle had a visible fracture, it broke. $8 and a week to wait, I glued the needle, and reassmebled. Now this old speedometer is working smooth and quiet.
