Alright some quick and good context first:

I bought a 1981 rx7 from a guy who already took off the OEM 4 barrel Nikki carb. Problem is he already disassembled it and frankly left it very unorganized. I was able to find out what parts I do and don't have, well the parts with actually numbers available on the Part Index manual you can find on Foxed.co. along with the carb manual featured on there.

The issue now is that I have no idea what bolts or screws I'm missing since they don't have part numbers, just standard part numbers which I've already made a thread about.

Rebuilt kits can give me the washers and the gaskets no problem but are there any hardware kits out there that aren't specific to this Nikki carb or really Nikki at all that features the same size bolts that are used? Thanks!

 

One more thing to add, I am also open to the idea of just getting a giant kit of like hundreds of different metric sizes that are built to really last for awhile in an automotive environment if anyone has any good recommendations.

 

Try Atkins Rotary or MazdaTrix. They both have them. One thing to be aware of with Atkins, they will show Mazda part numbers on some parts, but they are not genuine Mazda parts. The part numbers are only for reference. The issue is that you may not know if the part is from Mazda or not.

 

I have found the the same issue with orders from Mazdatrix too.

 

I ended up getting a carb kit from Sorenson on Autozone and I bought a metric bolt kit from somewhere that's a few hundred pieces and I'm just gonna start guessing sizes for this carb until one fits snug lol. Thank you guys for the heads up on that one kit though I was considering it as an option!

 

most of the hardware on the carb is the same thread size, and it only varies in length.
some of the really old carb modding people like Sterling, used to replace all the screws with allen heads. so once you figure out the thread size (M4?) and length, the hardware store or Belmetric works

Mazda also uses JIS standard for their hardware, so like an M6 is a 1.0 thread with a 10mm hex. i'm not sure what the JIS is for the carb stuff, but that is what it will be

 

Awesome, thank you for confirming that! I just bought a big automotive bolt and screw kit online that has all of the metric standard sizes so I should be good and ready for the carb. I think the only thing I'm missing now is the weights for the check *****, I was able to order replacement ones off of McCalister-Carr (butchered that) but the weight are bit trickier because I don't know how much they are supposed to weigh and all that
