Hi, If you take off the rear hub cap and the halfshaft has a thread and nut on the end
then its definitely a 6 spline fitting halfshaft to diff.
ps. Im looking for another P4 3.9 diff. if anybody's selling one.
thanks Jeff.

Hi, It sounds like your spare is a later diff. check your early diff. the top bolt hole will be at 12 o'clock, and approx. 10½" flange to flange The later diffs. and axles have the top bolt hole a whisker before at 2 minutes to 12. and are approx. 9-1/8" flange to flange. If it wont fit your car 4.8...

Hi, If you count the number of teeth on the crown wheel / 47 teeth = 14hp 5.22-1 OR 44 teeth = 12hp. and speed14 4.88 TO 1.
cheers Jeff.

Hi, the diff. casing is very different to the post war models, there a few company's rebuilding landy diffs. Perhaps with a little engineering work one of these could fit an up rated crown wheel & pinion to your diff. It would be interesting if someone could do this, but I intend upgrading my 37 20h...

I've been watching this car on eBay there were lots more photographs, it finished a couple of days ago, don't know if it sold. Apart from the terrible home made air filter pipe the car looks a Bute. Prices are very different for different models and condition, this one looks really good but if I was...

Hi, the diffs after the war up to p5s and early 4x4 with 10 splines are interchangeable. The only Straight Swop option for your 1935 6 spline 5.2 diff. would be a 4.88 6 spline out of a 12hp (there's one on eBay) On my 1936 14hp (rod brakes) I changed the axle for a 1946 10hp then fitted a P4 diff. ...

Hi, I've had a few of this model, unfortunately the very low 5.2 rear diff. and 17" wheels at 1000 rpm gives you little more than a brisk walking pace. I my opinion the same year 12 hp model is a livelier drive. fitting a higher ratio diff. makes the car 100% better, I used a 4.3 P4 one. cheers Jeff...

Hi Steve,
Only the P2 10hp wings were similar to the P3s perhaps its one of these
All other P2s had a 3/4" bead pressed round the edge of the wing.
The large slot holes in the wings give quite a lot of in/out adjustment.
cheers Jeff.

Hi and welcome to the RSR website. Your car looks a great very original example, I've had a few of these models over the years saloons & sports. If your wondering about the kink in the hose to the thermostat its because these are prone to rot & yours has been replaced with one off a 4 cylinder model...

Hi,
Perhaps the flywheel has been off at some time and refitted 180 deg. out.
