Exhaust Manifold Studs

[Mike92STX]

Can someone tell me the size of the exhaust manifold studs on a 04 Ranger with 4.0 V6. The Dorman part number is 03129 says 12mm - 1.75x 62mm. I thought I could get the part number and size from a Ford web site but the ones I tried were real stupid. I put in what truck I have and give parts for newer Ranger and some of the parts weren't even for the exhaust.

M12 would be huge for exhaust studs... they’re m8, but I don’t remember what pitch and length and off-hand.

My son found some on a Autozone site that said 8mm -1.25 × 25mm. I checked them and 25mm seems short.
Thanks for the info.

25mm is way to short...

I'm guessing closer to 75mm is more like it.

Yeah. 25mm is about 1”... I’d have to guess they’re over 50mm long.
