Does anyone know where i can get some exhaust manifold studs (the studs it uses to connect to the y-pipe)? Mine are all rusted to hell since we replaced my oil pump (had to take the y-pipe off), and 2 of them also broke. I got some from autozone but only to notice as soon as i put them up next to the older ones they were to small, yet the package said they would fit on my year 5.0. Any of you know where i could get the right sized ones? Thanks!

 

Guys please help! I really need these things because i really need to get my truck back on the road as its my daily driver. Ive been to autozone and they dont have the right sized ones. They only had 3/8"s studs. These seem to be metric. I tryed Summit Racing and they dont have the studs for anything period. Would Napa or somebody have them? Cmon somebodies got to know??

 

I got mine from autozone. They had a whole box of assorted sizes. Mine is a 78 F150 with a 71 460, so it's definately not metric.

What year truck and which engine? Did you try a Ford dealer?

Most muffler shops have a special tip for their MIG welder that will weld another stud on top of your broken one. This saves a lot of installlation hassles for new studs.

What I have done for my exhaust in the past. Knock or drill out the studs from the exhaust manifold. Replace them with 1/4 or 5/16 grade 8 long bolts, nuts, washers. A lock washer on the bolt side and a lock washer on the nut side. The lock washers will work so you do not need another wrench or hand at the top while you are fastening from the bottom.

If you have three holes/studs per pipe, then three 1/4 grade 8 bolts will have plenty of strength to hold an exhaust on and you can usually get enough pressure (20 ft pounds) to get a good seal. I use high temp antiseize on the bolts. Though if they ever rust through they are pretty easy to snap off with an impact wrench to replace them.

If you go with 3/8 bolts you might find the washers/nuts/socket will not fit inside the flange on the exhaust side.

Most NAPA stores have an excellent assortment of bolts AND studs.

 

Thanks for replying. I got a 91 F150 with the 302.

 

I'm guessing that your truck is new enough that the dealer should stock those. If not, they should be able to order them.
