On my '47 both the choke and throttle linkage between the firewall and carburetor is composed of a two-piece rigid metal shaft (about 1/8 inch diameter) with a hard rubber fitting half-way between, apparently intended to provide flexibility and isolate engine vibration and normal engine movement. I believe some cars had the one-piece choke cable assembly held by a bracket on the carb body. My existing rubber isolators crumbled due to age and engine heat and I put a small piece of 1/2 inch copper pipe, clamped, over them. I want to keep the original dash board knobs. Options: (1) Is there a source for a new replacement to match original, (2) a more durable solution - a modern choke cable kit to replace them ? cut-to-fit or not, or (3) easy way out is using small clamps and some firm rubber tubing i.e. gas line to substitute the original rubber fitting.

The rubber joints are available from the usual vendors. However, they are crimped on, no easy task to R & R. Read this discussion: https://www.earlyfordv8.org/forum/viewmessages.cfm?forum=18&topic=14131

I have a 42,46, and 1948 Fords and this is how I did mine. On the old joint I removed the joint with a Stanley knife. The end on the carburetor I cleaned up the portion going into the joint on the wire wheel on my bench grinder where the end coming from the firewall I scr*ped clean. On the new joint I carefully removed the metal ends with a pair of plyers. Went to NAPA and got two round metal fuel line clips of the appropriate diameter. Lubricated the holes , slipped joint in between the rods then moved the fuel line clips to the ends of the joint. Not the correct procedure for a Dearborn car but I have not had one come loose and they function well. P/N is 91A-9702 from Third Gen. This message was edited by 1942deluxe on 7-3-23 @ 7:11 AM

I don't have a Dearborn car either. I haven't taken my existing rubber connectors apart but they appear to be fused (glued?) in some manner to the metal shaft ends, no clamps or crimps. The ends of the metal shafts are enlarged and imbedded in the rubber. The basic design of the stock linkage seems awkward compared to the later use of choke cable. On "the far side", more involved, less original and less interesting, one could extend the under dashboard choke cable direct to the carb and fashion a bracket to hold it there.

Here's two photos of mine on the 42 coupe. The fuel line clips may be overkill but I didn't want them to have any chance of coming apart. PM me if you need me to walk you through it. Agree they could've made a simpler set up. We won't even discuss the fan assembly..... John

1942deluxe I see your flex joint has exposed metal each side of the rubber connection; my existing doesn't. Regardless I'll cut away the rotting rubber and use a piece of stiff hose and clamps. Regarding the "fan assembly" - agreed. It's just another maintenance item and I seem to spill some of its oil when I have to remove/replace it to work on the distributor. Considering my non-concourse vehicle, Bob Dake is selling a replacement that has a sealed bearing instead - no maintenance. I went for it - perfect fit.
