That will work no problem. Any air in the system will bleed out the top. When refilling coolant just be sure to bleed the system as with a normal heater installation

What you don't want is to block the hose, which can create an air pocket. On the other hand, what Nissan did was block the back of the cylinder head which is OK if there are no heater hoses (as in a STD 1200 with no factory heater)

That is my guess: completely interchangeable

The A15 crank will only fit a "G34" block A14 (1980-up). The earlier A14 blocks do not have the relief cutouts machined in the sides to take the larger A15 crank throws. Also some G34 for A14 may not have this modification (there are two G34 part numbers, one for A14/A15 and one for A14 only)

OK, Ive checked the official source. According to the Datsun Parts Catalog there are two part numbers

12200-G3400 CRANKSHAFT ASSY
12200-H9700 CRANKSHAFT ASSY

Both are for the same years. The G34 is for A15 MT applications and the H97 is for A15 AT applications. So AT or MT is not in the part number itself

The Catalog indicates that the crankshaft comes with two other parts:
* 12200A PLUG-CRANKSHAFT OIL HOLE (quantity four, various part numbers)
* 32202-18000 BUSHING-CRANKSHAFT
these parts are the same A12, A13, A14, A15

now im wondering if they actually put a pilot bushing in all of them. It doesn't actually state that it comes with it, but the drawing shows an inclusion. But maybe that's the H97 vs G34 (with or without the bushing)? Hard to believe they'd be including one with the "Automatic Transmission" part

I believe they are substantially the same. I can't recall ever hearing about any differences. G34 is the revised A15 model code and H97 is a B310 1980-1982 model code. It denotes some change, but it may be minor

The "AT" and "MT" may be something that an eBay seller tacked on. On the other hand if Nissan sells them this way, then the AT version may not have a pilot bushing installed. Or something. Just guessing. Nissan "service parts" sometimes have a few letters at the end of the part number

Datsun 1200 doesn't have the shortest wheelbase

Sure it's good for rallycross ... but is the 1200's wheelbase too short?

I was just watching the latest Junkyard Crawl with Steve Mags (ex- of Hot Rod magazine), and he said the GEO Metro had a very short wheelbase

I had thought the 1200 had the shortest wheelbase of any sub-compact (non-Kei) car. I knew the old Mini was shorter but that's a smaller-than-subcompact car

I guess short wheelbase makes a car harder to drift?

You can do it either way

* Route heater tap on cylinder head back to heater pipe (just without heater). As you note, this is how it works from the factory when the heater is open (lever fully to HOT), back of cylinder head is connected to radiator pipe

or

* Block the tap on back of head. This is what Datsun did for STD 1200s without the optional heater

Nissan part number 00931-30610 PLUG-HEATER OUTLET HOLE

Heater hose plug for cylinder head (as fitted to no-heater models)

2.8kg is "ultra light" is jerky a street car, but would be superior for accelerator on/off racing

The dash number is the version, often it has no discernable changes. B110 originally came with LT-135-13. Some of the later versions may have different ears for use on a Mazda or Isuzu or somesuch

The exact interchange is as follows (USA models, probably same/similar in other countries). Basically if it's a Datsun 35A, it'll work. In USA most Datsuns used 50A units which are physically bigger
* B110 1970-1973
* B120 1971-1985
* B210 1974 standard duty
* 510 1968-early 1971
* 521 1969-early 1971
* 620 1973-1979

The best one to use is the LR135 from 1979-1989, it is exactly the same size and has internal regulator. Just unplug the existing regulator and jumper two wires. See LR135 for more details
