.120" should make hole 9 the same size as hole 11. you could drill both holes to 1/8" which is .125"

installing the Sonnax valves is also highly recommended.

 

hate to bring this thread from the dead but does anyone have the f150 separator plate photo and with number location. all im finding is plate pic and number locations from crown vic's not anything like what my 99 F150 plate looks like.

 

Getting lost with all the different hole numbers. Which one do you enlarge for a firmer 3-4 shift?

 

i did the jmod on my son;s 2000 F150. Works great.
