New throttle body. Old gasket?

[mxsuprastang]

Hey guys I just bought a new Ford racing 70mm throttle body but it didn't come with a new gasket. I assumed that since the description said "kit" it would, but it wasn't so. So now I have to figure out a couple things. 1.) WIll my old TB gasket work though it is old and OEM size (65mm i believe). 2.) If the old one won't work, can I just get a new OEM one from my local checker auto store that is also OEM size. or 3.) Must I buy a 70mm specific gasket? I noticed that the BBK TB reuses the stock gasket, so I was just curious if the Ford racing one would too...(http://www.americanmuscle.com/bbk-70mm-throttlebody-96-04gt.html) <---BBK TB

just trim it to fit your new one so its smooth, if you have it at 65 it will kinda have a non smooth flow. so kinda port match it. as long as it doesnt leak then your gravy

If you cant find one just buy the material from any auto parts store and trace it with and x-acto knife.
