The rods and caps in hand are aftermarket - they did not have bolts/nuts with them. I have established that the OEM-size 8mm bolts will fit. At this point, I won't be making the changes needed to use 9mm bolts. Thanks to everyone for your responses and to Slow Loris for pointing me in the right direction. I will now order the ARP kit.

Each/Every, Thanks in advance for assisting. (The Search wabbit hole on Ratsun did not lead me to an easily-found/coherent answer to my query). So: I purchased new connecting rods for my engine build. (L18) The only rod bolts/nuts I have on hand (8mmX55mm - which definitely fit the rods/caps) are of unknown usage/condition (though clearly OEM). In the interest of Peace of Mind, I want to replace all of those bolts/nuts. (I have a new set of main bearing cap bolts and cylinder head bolts in hand). My local Nissan dealer searched their parts system for the part number I supplied (12109-A3510) and reported the only (superseded) parts listed are connecting rod assemblies. The ARP website does not appear to have a listing (that I could find). If someone can provide an ARP part number for a bolt/nut set or another source for the bolts/nuts I am seeking, it will be much appreciated.

See you there.

bananahamuck: I did buy a roll of cork gasket material from NAPA. ($9.02) Yes, making my own will be easy. In this case, the transmission was very clean inside and out - and was evidently "harvested" from a low-mileage 510 quite some time ago. A replacement cork gasket will certainly last for as long as I will need, and just feels better to me than using (even modern) goop. As for the cost of buying from the online seller, it is really a matter of principle for me. I have purchased a lot of parts (for my Datsun Roadsters) from this source, and it just seems like the recent price increases are somewhat excessive. My hope was one of the typical aftermarket gasket providers would have a listing for such a (formerly) common vehicle, but as you note, the newest Dimes are 50+ years old now. Related to this, it is also a common experience for me to find an online seller has simply found a supplier with stock, buys them on the cheap and quadruples the price. Such is life. One would hope the Datsun community would look out for each other - which it does, for the most part - but self-interest is a motivator for many.

datzenmike: The distributor I intend to use (for my L18 SSS build) came off the Japan-sourced L18 engine I once had, and appears to only have D409-54K stamped on it. There are no other numbers (such as 22100-?????) evident. On the bright side, the chart shared by DARIN 510 confirms the application for this unit is for '70-'74 L16 SSS & L18 SSS. So, given that the dizzy in hand is in VGC and is appropriate for my current L18 SSS setup, I am confident in using it. One other cool thing of note: The distributor came directly from Japan with a blue cap and blue rotor. These appear to be OEM type parts, and somehow, I found the same blue parts - new - in my stash. Thanks

Loving this conversation. The chart shared by DARIN 510 answers the questions regarding the numbers on the distributors I have in hand. And, the insight by datzenmike will be most helpful when tuning my build.

datzenmike nailed it. That is the gasket, for sure. It seems Crashtd420 has found a source, and I now know that part will fit. Just seems like an excessive price to me. One would hope Felpro or some supplier would have a listing. No doubt someone has a few of these sitting around somewhere. Thanks.

Initial inquires have left me stumped. The local Nissan dealer is unable to supply a PL510 4-speed transmission pan gasket. (PN 32162-14810) This is not surprising, but a few other stabs at sourcing aftermarket substitutes have yielded nada. Who has info on what/where to buy this part? Thanks

Thanks All for your feedback and input. After careful examination, the numbers I shared appear to be the only ones present. Also, it is evident none of them (regardless of the vacuum advance threaded/not-threaded attachment points) are not for a Roadster - as they have a different base with a tach cable drive. So, the idea of using the SSS L18 unit remains top of mind.

Sorting through the old stash of L-series 4-cylinder distributors today. Many similarities, some differences. (All on hand are single-point type). As for identification, they seem to have stamped marks (ID for characteristics?) that may mean - what? One thing I know for certain is the unit with the blue distributor cap came with the Japanese market L18 SSS I bought a very long time ago. Thoughts on these? I'm inclined to use the SSS dizzy as my build is an L18 with the SU carburetors. What says the tribe?

Thanks iceman510 and all who replied. The tribe comes through again.

Here is a bit of mystery: So far, the usual suppliers are coming up empty in my quest to find the two-hole fuel line grommets for PL 510 that are located in the RF corner of the engine compartment (below the factory fuel filter location) and under the fuel tank where the lines pass through the floor of the car. Does anyone have a source for these? Thanks

Looking ahead as I reassemble my 2-Door Dime: Any suggestions for more modern/recent front seats that will fit well in a 2-Door? I would prefer to stay in the Nissan family if possible - and like separate/adjustable headrests of some type. (No high-back one piece). Not in love with excessively high side bolsters, so there's that. Of course, whatever is found must tilt forward to allow rear seat access. This is really wide open, but something along the lines of a Sentra (maybe?) or any model that isn't long extinct and may be a likely donor seems like a starting point. Cloth or vinyl would work, (leather drops to #3 on my list) and I do have some fabric that very closely resembles the original (black) vinyl if recovering is needed. In the alternative, a pair of original seats in VGC might work as well. (The set I have is junk. Too far gone to revive, IMO). What say you, Ratsun folk?
