how do you get a ford explorer intake ready to run on a mustang?do you have to plug holes or anything?

 

bolt it on and transfer over your stuff off your intake and any left over holes if any plug

only area to play with are the vacuum lines on the underside of the upper.
I think I also read somewhere that the bolts for the lower were a different length, not sure of this but if you have the bolts from the Explorer I'd use those, or buy a set of ARP bolts.
