Any sources for these? Thank you. Could use an air cleaner too.

What parts are you looking for?

Brake master cylinder, rubber hoses, brake shoes, related hardware kits. Also looking for an air filter assembly. Thanks much for any help. Brian

Okay, here's a quick run down...er maybe lengthy.....

Brake MC - try to rebuild yours first. Its a 3/4 bore. I'll have to find some part numbers for you. Or see eBay for 3/4 inch bore Brake MC rebuild kit.

I just double checked my brake parts box and all 3/4 in O-rings are the same in and outer diameter, meaning you can use the rear or front brake cylinder O-rings on the Brake MC plunger. It requires 2 O-rings. So yes, you could use a rear brake cylinder rebuild kit, 3/4 diameter, and have the two seals, but you are still missing the front boot, pin release o-ring and circular clip.

I have purchased all my hoses at O'Reilly's Just remember they are 3/8 diameter male and female ends with 24 pitch. So you can tell them this and they can get you the different length hose for the front (~15inches) and rear (~17 inches)* All parts below are Brake Best (BB)-

BH36737 - front brake hose, obviously you will need 2 $14.87 ea
405 and 406 are your front and back brake shoes; $19.39 for the 405s.

I also have a BB 511 part number for rear brake shoes (these say 520, but they are all the same 10 3/4 brake shoe for all Datsun 320, 520, 521, 620, and 720 with drum brakes)
Rear brake spring kit, if you need it is BHH 17219
H1457-2 - these are the clips for the brake lines as the brake lines do not have the outer threads, I think there are 4 or 5 in a box. One box will do the brakes and the clutch
BH64840 is the clutch line, Please double check this one as I might have put my clutch line in the wrong part's number box. It should have one funky looking end with a 3/4 long hex head that goes into the slave cylinder.

Rear Brake hose, sorry can't find exact BB part number but is ~17in long hose. THIS HOSE REQUIRES MODIFICATION TO THE FRAME MOUNT. Yes, you will need to enlarge, file, grind out, or drill the brake mount on the frame until you can fit the hose through.

FROM NAPA
Okay, NAPA lists quite a few parts for the 320, you just have to click through the Datsun 410, 411, 320, and 520 and by each year to find the compatible part. Be advised some of the pictures are not correct or they may not know what the right part is.

Here's the link to the '67 520
http://www.napaonline.com/Catalog/Resul ... %2b2018052

Always open the box first, ask the dumb question before walking out, and always, always ask if there is an additional shipping charge YOU have to pay prior to them ordering the part.

Front brake rebuild kit -is UP 643. The picture shows the kit for a rear wheel cylinder but the 520 has the same brake set up as a 320. 3/4 inch bore (or more exact 19.05mm or .77inch per Mr. Nismo's 520 manual)

Back Brake rebuild kit is UP 818

NAPA list brake shoes as TS406 rear ($15.99 + a $6.50 core charge {didn't know that}) and TS 405 front ($21.99 + $2.50 core charge) ----I did not pay a core charge at O'Reillys

Do not have an extra OE type air cleaner, Any 320, 310 Bluebird will work with the Nikki 2D-30C. I'll have to confirm the 520's J13 D2630A-5A Nikki carb, it might have a larger diameter assembly choke. If the same, I might have a few extras in various states on repair.

Let me know what else you need.
