Does anyone know of the proper tap sizes for completing my Expy seat swap and Lariat center console swap?

I need to go buy them, but do they usually come in a set or do you have to buy them seperately?

 

When i did the seat in my 01 screw and my buddy's 2000 scab i just used the bolt and let it self tap, worked great!!

 

The bolts for the seats and the reinforcements that you actually thread into are meant to be self-tapping. There are a lot of parts like that on fords, especially when you buy OEM body parts like hoods and stuff like that where you have to take parts off the old part and install it on the new part. I think they did it to shorten their manufacturing time and to not require to have all of those holes tapped before hand.

 

I bought a cheap set of metric taps at Kragens, which had the two sizes I needed (that was 5 yrs ago ... I don't remember what sizes they were ).
