I just got an 83 280zx NA and had to take off the exhaust for the tranny swap.. two of the three header bolts snapped off...does anyone know if these bolts are part of the casting of the header or if the bolts are reverse thread and can be unscrewed from the header???

any help is great appreciated

and the haynes and clitton manuals don't have anything on these bolts

 

Welcome to ZDriver!

They are removable studs. See this thread: https://www.zdriver.com/forums/280zx-s130-forums-77/exhaust-leak-manifold-1982-e320zx-28500/

 

thanks man...I just got the car running today with the new trans and I just want to drive it but couldn't because of the exhaust bolts but, now I know what to do

should i replace them with oem studs or just drive out the wholes and put bolts through

 

I would replace them with OEM studs. I got mine from MSA, for not too much. (a buck or two) www.thezstore.com Probably would be best to speak to an operator. I don't think they list them in their store. Good luck man.

 

thanks guys...I really appreciate the help...and so far I'd say that this forum site has the best response and people willing to help another z owner...thanks once again
