Gents, as one who has done the 5 speed conversion, I can say simply that the car has a BETTER vibe now. The thing is awesome. And to the untrained eye it's hard to tell there's any "foreign" parts in the car. With the hood closed you can't.
The car has all the same traits we have always enjoyed, without the niggly shortcomings like no synchro 1st when in traffic around town, and the shortness of gearing when cruising down the highway.
That synchro 1st is worth the price of admission, the overdrive a huge bonus.
Oh, and BTW, to my knowlege, P.A's Morris Service kit is the only one that uses a Datsun clutch. A bit bigger and stouter than the original, but it does require machining of the flywheel which Paul will do....for a price. Great kit though, very high quality if a little pricey.
I think my whole conversion came in at about 2 grand which is steep, but I would do it over again, that's how much of an improvement it has made. For that I got a rebuilt gearbox which accounted for nearly 1/2 the cost of the kit, new rear mount, machined flywheel, speedo angle drive, new performance Datsun clutch and all the fancy milled aluminum bits like back plate and slave cylinder mounting bracket to make it all work, shortened shifter lever, roller T/O bearing with fork and yoke. Oh and shipping too, which also required me to send my flywheel to Oregon for Paul to fit the clutch to. Great guy to deal with, but old school, no web site just the phone and email.
5 gears rule and don't be scared of putting this kit in ANY Spridget, even a 948. 5th isn't that big a gear the 54 horses can't pull it.
A highly recommended upgrade for these cars from guy who used not to see the point of it.
