Have a 4100 C5AF-F carb, that did not come on this truck a Ford F-250 with a 390 standard engine with automatic trans and manual choke. Had it on the truck for years and seem O.K, know its time to rebuild. Have carb kit for it but not sure on the float settings primary and secondary and the pump rod setting in or outside and 1-2-3-or 4 and any other settings this carb should be set up for use in this truck Thanks

spec. listed in my rebuid kit text shows 29/64" DRY, both pri. and sec. for '65 390 A/T. I always set it WET, per the shop manual, @ 29/32". Accel. pump lever is inside and #3. The plastic secondary arm has a "tit", which fits into the diaphram's hole, as opposed to the metal arm's hole, and the arm's pivot hole is also different between metal and plastic. If you must use the metal one, you will have to do some fabricating.
