Dorman 03147 Front Exhaust Stud Kit 3/8-16 x 2-1/2 In. and 3/8-16 x 3-1/4 In. Compatible with Select Models

I used them on a 1974 Jeep with 258. I used the short studs

Chevrolet 1970 350 engine I had to replace a stud that was missing it fits perfect even when amazon says it does't

Had to reuse 1 of my old nuts/bolt since this item had a brass nut lose it's threads, peeling off along the bolt. Also all of the bolt types with the bubble section on them had a defect on the short thread side of the bubble (as if a Dremel like grinder had bumped it). Nuts set fine to start properly, but started difficulty at the defect point which was about 3-5 threads in and caused a difficult thread down issue. One couldn't just handspin any of them further once contacted with marred section of thread. This is likely why it had eaten the threading on the 1 nut, even though it wasn't cross threaded.Reason I rate it three stars is that overall has historically been a good product. I have used these many times on various vehicles thru the years without previous issues, but quality control slipped up on this batch.

Fit perfectly in my 1978 chevy C20. Had no issues with installing into exhaust manifolds.

Great quality on product, fit perfect. Used this set up with brass nuts for years.

the price was great and the fit was perfect everything needed is included great product

Purchased this hardware with exhaust system because it was recommended. Due to rust and design of flange, it finished job much faster. Thanks Amazon for recommendations, this one made a difference!

This kit contains three 2-1/2" studs and three 3" studs. It does NOT contain 3-1/4" studs as described. My application need 3-3/8" OAL studs or the nut won't catch. 3-1/4" may have worked, but 3" definitely did not work. I could not use this kit. It is described wrong on the internet and wrong on the actual bubble pack. Be advised.

Came early, reasonable price, good quality, thanks.
