"Told" by who? The problem would be a clearance issue under the floor.

I'm going to assume that the kit that you are looking at comes with the pedal assembly and that is the issue as those do not have provisions for a clutch pedal. The fix for that is to find a booster/master cylinder with a bracket and no pedal assembly and use you stock pedals.

This is only an EXAMPLE and not a suggestion that you buy this specific one. The same outfits that sell the whole kit with pedal usually sell the same small diameter booster and master cylinder assembly that you can fab a bracket for and by building a stronger push rod (beefy) you can mount the assembly under the truck and use your original pedal. A few on here have done it on TF trucks and when they wake up maybe they will be kind enough to show the photos of what they did and explain how they did it. https://www.ebay.com/itm/1960-1966-C....c100005.m1851

The manufactures of those kits with the pedal all think that we all run automatic transmissions.
