I can make you one. I would need to weld the new lever on the existing shaft from your C4. Those shafts are very difficult to find anymore. Since there was no Bronco C4 option in 1971 I need to make sure you have the correct shaft. It needs to have 2 slots at the exposed end where the neutral safety switch (NSS) would slide down on. If it doesn't have the slots you can't use a NSS. There are also length differences in the shafts over the years that affect the kickdown lever but if its matched to the year of the C4 it will work. In short, its best to use the existing shaft if it has the slots.
The lever also needs to be clocked correctly to put the NSS within it's range of adjustment. I have a jig for this. Correct clocking will allow the stock linkage to work with a stock steering column. If you have an aftermarket column you may have to adjust it's linkage to work correctly and gear indicator to be accurate. You will need to add the pivot stud (

The way this works is you remove your existing shaft and mail it to me. I attach the new lever and send it back. I usually have them back in the mail the following day. Then you re-install it. Its not a difficult job but it can be messy. You need to remove the pan and valve body to get the shaft out.
Cost is $50 which includes return priority shipping.
