Does anyone know the size/thread of the rear end cover bolts for a 99 GT? As stated in another post, I installed a Ford Performance rear end girdle last year. The bolts are already all rusty, and the car was in storage all winter. So, I want to replace the bolts with stainless ones. I just don't know what size/thread they are...without removing one and going to the store to match it up. It would be nice to know now incase I have to order.

 

I show them as being a 5/16" - 18 X 5/8" long

 

Thanks Randy...that saves me some time

 

no problem but I just thought of something, the 5/8" is for a thin metal cover and the girdles are alot thicker in the flange area, so you might need them to-bo closer to 3/4" or even 7/8" long

 

I think the ones included were 1inch or even 1.25 inch.

Just a quick question: the stock size, 5/16- 18.....does the 18 mean threads per inch?

 

thats is correct....

 

Hey Andy, 5/16x18x1.25 one and a quarter inches.

 

Thanks everyone. I remember that they were pretty long!
