I'm replacing all the hard lines on my 78 RX-7 Savanna, however, I can't find the right fittings/bolts anywhere that i need to put on the end of the lines before flaring them. I work at NAPA so I know they don't have them...even any adapters. Figured i'd see if anyone else had done this and if so where they got them? I can't reuse the old ones...the reason i'm replacing the lines is because the old fittings are shot. I tried searching, but I can't seem to find anyone else that has had this problem. They are an oddball thread not the standard metric thread. 10x1.25 instead of 10x1.00.

Thanks,

I just used the standard metric threads for my 84 GSL-SE. It seems to work well, at least I have not noticed any leaks yet. I bought the hard lines from Murray's by the way.

 

If you are going to the trouble of redoing all of the brake lines, then I would suggest you upgrade the front struts and rear end to FB units. Eliminates the fitting problem and makes part sourcing easier, especially struts.

 

Well the struts that are on there are in perfect shape...the only thing my car needs to get back on the road is the brake lines replaced. I have the lines all cut and bent to shape...just no fittings lol, i might try a hydraulic company that also makes stainless lines and see if they have some kind of adapter...figured i'd try here first and see what other people had done.

 

You may have to buy pre-made lines that have the fittings you need, then cut the lines and use the fittings.

 

Just use your old fittings.... remove them from bad lines and put them on the new lines BEFORE flaring the new lines (3/16").

 

any of the pre-81 mazda's such as 626 & GLC to name a few have the same thread pitch. Those are easy to get in my neck of the city. how much do you wanna pay per fitting.

 

Or try to find another SA that's junk and try to salvage the fittings. Also other Japanese cars from that time frame may have the same fittings. So you may have to go to a 'yard with a can of PB blaster and a 10mm line wrench and see if you can come up with anything.

 

Thanks for the help everyone, turns out Foreign Autoparts sells adapters so I can put regular metric fittings on the lines then screw the adapter to those. Unfortunately the reason why i'm replacing the brake lines is because most of the fittings are shot that are on there now lol. The adapters are 3 bucks a piece...so could be worse I guess.

 

I just replaced all hard lines in my SA also. I bought a 25ft roll of 3/16" brake line from Napa for 25.00. Easy job. Used all my old fittings..

 

My fittings are a bit chewed up as well. I'd like to find replacements and not go the adaptor route. I think someone on here said they went a hydraulic place to get the right ones. It would be really nice to find these new online somewhere. Is that thread pitch you gave, 10x1.25, the correct one for the original ends ? Maybe I can search on that.
