hi guys i just scored myself a 63a a series box and want to know whats involved in hooking it up to a A15 1200 coupe. normally by now i would have done some home work but it kinda got sprung on me today.
so any help would be appreciated.
thanks kurt

Is it a 63a L series or A series?

its hydrolic clutch so sorting that is a biggey, then crossmember, driveshaft, oil it

A series sorry about that, so it bolts on but i need to change the clutch. and thats gonna be hard coz i have a booster on mine
can i use any l series parts for the swap/spares

a series run a 180mm wide clutch disc, the l series run a 200mm. the 63a spline is the same as the l series, so you need to either have your flywheel machined and redrilled to accept a 200mm disc or get a clutch joint to make you a 180mm disc with the same spline as the l series 200mm one.

the output spline at the back is the same as l series too, so a new shaft will have to be made, my shaft was already fitted with 180B unis, so I just knocked the original front yoke off and grabbed a 180B one from the wreckers and whacked that on and got it balanced. You might need to get something made.

Depending on whether your coupe started life as a manual or automatic, you may need to rework the tunnel slightly to make it fit in, especially around the reverse light switch on the box and the original crossmember mounts in the tunnel. A new crossmember will also have to be made.

Nothing to it.

I believe the clutch plate will be Datsun 510/1600. Same for drive shaft output.

so do i use a l series pressure plate and clutch on my a series flywheel?
and what did the 63 series gearbox come behind in an a series in australia?
thanks guys
and its a race car so ill just delete the reverse switch and wire it up manually

You should be able to find a tailshaft to suit without modifying one. A-series Auto tailshafts have the same yoke as L-series boxes, so even if you have an H165 one from a sunny could potentially fit.

In both my 1200s I am using 1200 auto tailshafts.

You'll need to remove the factory gearbox xmember mounts form the tunnel, and make a new xmember. I bolted mine through the floor, with plates on top to stop the bolts pulling through. Converting the clutch to hydro isn't too hard. It may be more difficult for you since you have a booster. You'll need to have your flywheel redrilled to take the 200mm p/plate. You just use an L series clutch and p/plate. I got the heaviest off the shelf p/plate I could find.

has anyone tried just swapping the splined 1/2 of the yoke from the 60A series driveshaft over to the driveshaft from the 1200, are the U-joints that much different?

I have not put them side by side and looked at then either, maybe it's self explanatory when doing so.
