Got a few more updates to share.

I've slowly been gathering parts for my q-jet. I needed some things like the divorced choke linkage and some various fuel and vacuum fittings. I should have everything I need now. I plan on installing the carb around the same time I replace my motor mounts, so that I can use a lift plate when the carb is off to hold my engine up.

Speaking of motor mounts. I discovered that the P.O. of my truck used the wrong motor mount perches. There are several different styles that vary by engine, vehicle, year, etc. Whatever he used was a front mount perch. Obviously that won't work for a rear mount application (unless you booger weld it in place like he did). I ordered some 67-72 motor perches that should fit significantly better.

My blinker issue is still ongoing. I might have made progress with diagnosis. My blinker fuse popped while I wasn't even in the truck. It was idling in the driveway. I verified the blinkers worked prior to walking away. When I came back they no longer worked. I have yet to duplicate this incident, but it suggests that I have a very small short somewhere that is causing gradual heat buildup. The first thing I'm going to try is replacing my LEDs on the blinker circuit one by one. I want to make sure the circuitry in the switchbacks isn't the issue.

Lastly. I got tired of my coolant reservoir. It was only a quart sized reservoir and it always overfills before my truck reaches operating temps. I calculated that I would need approximately 3 quarts to allow for expansion and drawdown. Just to be safe I ordered a 1 gallon coolant reservoir and then proceeded to make a custom bracket for it. I used 1/8" flat steel and bent everything with a hammer and vice grips. It took 2 days to get everything bent, drilled, and painted. But it came out great and the reservoir is very sturdy. A total of 6ft of flat steel was used to make the bracket.
