ok I know there are a lot of questions asked about this all the time and I have looked at a couple of how-to's and my question is in a 97-03 f150 how long does the pipe need to be? I know it should be 3" wide but how long should it be? I'm about to go to homedepot and get everything I need

 

if you get a 6 inch scrap piece youll have more than enough. check for a cut bin

 

alright thanks man I figured about 5" should be plenty

 

think my piece was about 4 inches but i dont remember i sucked I had to buy an 8 footer no big box store around here just a mom and pop hardware. not worth a two hour drive for a home depot..

 

awe that sucks.. I got lows and homedepot about 10-15 minutes away from my house

 

Yeah mine was about 6 inches too I believe

 

just got it done. used 5" long pipe and it was perfect. PAIN IN THE *** to get that pipe grinned down to fit

 

Haha yeah that was the hardest part for me too

 

That's why you use the regular stuff, not the schedule 40. You simply squeeze it with your hand and insert it through the wall.
There's no need for any thing heavier.

 

oh well it's done now
