Throttle rod length?

Just got a new set of control rods for 1930 coupe. The old ones were bent up a lot. The spark rod (17") and carb rod (10.5") went on great; but the 6" throttle rod will not fit without bending it a lot - the distance is only 4.5" between the connections. I would prefer not to bend the rod. I know that I can cut it and get a spacer to shorten the rod. Just wondering if this is normal. Most of the pictures that I looked at online show the rod not being bent.
 
I had the exact same problem. Drove me nuts. Turns out that the accelerator assembly that mounts between the engine and firewall was at fault. Even when I took it off, it looked o.k. But upon close inspection, the pivot shaft that runs between the two "Bearings" on the accelerator assembly was bent forward. Placing a straight edge along the shaft made it obvious. I put it in a vise and with a couple taps of a hammer, straightened it right out. The new throttle linkage then fit perfectly between the carb and accelerator assembly.
 
It is easy to bend these with a box wrench... wrapped around the end... just use the wrench as a lever and they will bend relatively easily.
 
had a similar issue caused by incorrect spark rod length , an issue with some of the spark rods from vendors: the correct ('30-31) collapsed length is greater than 17" (forgot exact size , 17 5/16? like from Brattons ) which should be verified with them before purchase. Shorter ones may require rotating the steering column housing out of position changing the position of the throttle rod.

What's the point of worrying about that/ There are no rods available anywhere near the right lengths for ANY of them.
