Hello?!?!?!?

 

With the attitude you have in the above posts nobody probably wants to help you. Also you aren't very clear on what you even have or need. A header and a gasket. Which header and which gasket? What nut or bolt size? Are you looking for the nut and bolt sizes to bolt it back up or socket/wrench sizes you need to take it apart? Answer these questions without being rude and maybe someone will help you.

Totally uncalled for.

Go look at your wrenches and fit them over the nuts/bolts then take them off and go take those to the hardware store like a man instead of telling people the **** off when you haven't done anything yet yourself.

 

You waited 7 minutes for a reply before posting again?!

This is not a real time chat room. It may take minutes, hours or days for a reply.

Especially one which could have been easily searched out as there is a thread in the Archives titled "Master list of bolt and nut thread pitches".

 

lol, you see this **** misterstyx? this is why i give the answers i do lol

 

But Barkz..he was lonely and after 7 minutes maybe he wanted a DOG..

I should start marking posts with "cookies" so you can deal with them..lol!

Head of that bolt is 14mm.

 

+1 stop being such a ***** OP

 

I didn't realize the "Master list of bolt and nut thread pitches" existed. Mainly because like fidelity101 suggested I take the old nut bolts to Autozone/hardware store and match up what I need.

Since the original poster hasn't replied back as to which header he has, let's just say it is the Racing Beat one, then buy this: Presilencer for 86-88 RX-7 Non-turbo - Man Trans - Racing Beat

and these: Down Pipe & Presilencer Gasket for 86-92 RX-7 - Racing Beat

And bolt it all together. Will not sound good with the stock mufflers but will bolt to the stock Y-pipe. If it is some other brand header then your on your own and unless you know how to weld or has a buddy who does then the exhaust shop may still be in your future.

 

Unbelievable... Douchiest most ignorant post I've ever read... I wouldn't help anyone with this attitude at all... Why in The F are you so bitchy before anyone even told you to start searching... Take the bolts out and go the the store and buy new ones.. This is almost a joke of a thread... Also I searched and I found the info you are looking for... In about 2 minutes... 6 minutes less than your were willing to wait for someone to respond to you...

 

Your nuts could have been replaced in the past. There are hardware size variations for same pitch threads. OP. you are asking a question only you can answer. get to your car with a set of wrenches, metric and SAE. and see which one fits best and use that one. Its not hard. The only thing i have left to say, i'll keep to myself and i'll **** off now. You're welcome.

 

Good point.

Wrench/Socket size for a nut or the head of a bolt can vary even if they are the same thread.
