I don't think so. For a B210, the Auto and 63A driveshaft are the same, but for B310 I believe the Auto driveshaft is a different length


> Also will the crossmember from the auto work?
Probably not for the B310. Perhaps the B310 5-speed (60A) crossmember will work. B310 has several holes in the body for the four B310 crossmember types

The 63A and Auto use the same rubber insulator (rubber mount). But the length of the B310 Auto differs from the 63A/B210 Auto

I’m looking to put a B210 63A 5 speed into my B310. I was told I can use a 3n71b auto driveshaft...is this true? Also will the crossmember from the auto work?

To enable an L-series 63A to fit behind an A-series engine:

1. Remove the front case (split the transmission in two). You are left with the sandwich plate, gearset and rear extension housing
2. Swap the input shaft from an A-series 63A (or machine the L-series shaft)
3. bolt on the front case of an A-series 63A

Once you have the 63A bolted to the engine in place of a stock Datsun 1200 gearbox, see the writeup at Transmission Interchange. It requires:
* tailshaft swap
* tunnel mount swap
* hydraulic clutch pedal setup

Hello
Just picked up 63A#3 dogleg shorty to put behind my A 15.
Any info regarding swap much appreciated.
Cheers Darren

I have done it... got L bellhousing A63 and i change A motor belhousit it. Input shaft modifield A motor crank.

Ive got the 63series behind my A15 turbo.
Love the 2nd to 3rd gear shift of a dogleg
Yes - Its worth money here in OZ
Seems like sacrilege to mod it.
Would love a spare

I have a 5speed 63A that was previously bolted to a L series engine and could offer a solution here.. will send you a PM

No I haven't done the swap. I have a 63A box for an A Series already. I bought it online for US$35 in Cincinnati OH and I had a friend ship it to Australia, probably 12 or 14 years ago. The freight cost me $250 back then!

I don't have a soltion to your dilemna other than to suggest that you use the 63A yourself. They have slightly better ratios than a 60 series box and they're much more robust. Plus I like the dogleg shift - mostly because it's different

Yeah shipping to Australia is insane. Was quoted about $1000 to get this shipped over there.

Looked at TechWiki under Parts for 63a and it showed part numbers for A & L input shafts on top of each other:

32200-N6700 GEAR ASSY-MAIN DRIVE A14
32200-21100 GEAR ASSY-MAIN DRIVE L16S

Which tells me they are interchangeable. Have you done this swap of parts before?

@TexasMidget
Unfortunately you're in the wrong country. Your 63A box is worth good money in Australia.
The guy who wants to acquire a 63A box for his 510 is in the wrong country. 63A box for an L Series are dirt cheap here.
Anyone in Australia who would like to acquire a 63A box to put behind their A Series engine is in the wrong country. I reckon you would have to pay A$1200+ to get one.
And anyone who's thinking of shipping a front casing from US to Australia or from Australia to the US is about 12 years too late to get access to reasonable postage charges or surface postage rates. (sigh)
