Hillman IRS part?

Jay Laifman · Feb 1, 2020

We're trying to identify the rear hub and outer stub axle that is on our Elva Mk6. It does not appear to be an official Elva part. We're wondering if it might be a Rootes part. It has a 4.5" bolt pattern. And the bolt that holds the hub to the axle is actually metric. I don't know when English cars would have started using metric on parts like these.

At least one other Elva MkVI does have the same hubs, but most have a different one. We have looked at Triumph and Datsun with no luck.

Thanks for any help.

Jay, Imps have a 4" wheel bolt pattern.

Thanks! Sometimes knowing what something isn't is just as valuable as what it is.

Jay,

It's a wild guess but maybe a Datsun 510 or 240Z?

Good call, Datsun used 4 X 118mm IIRC which is pretty close to 4.5"

Datsun uses 114.3 which is 4.5.. 240/260z and the 510s

Contact the folks at AWS Engineering. My guess is they'll know exactly where it came from.

Jay,

My suggestion was from a quick search for 510 hub pics and I think I found some with that general shape - but front hubs. Upon looking at your hub pic, is it possible that your hub has actually been lightened from a round or rectangular shape? The edges of your hub appear to have been hand ground leaving some irregularities that should not be present in a machine formed piece. I think possibly the best identifying aspect might be the shouldered studs. I am guessing those shoulders are for locating the brake disk or drum instead of the hub central register. I don't recognize the studs but someone else might.
