Hi guys
Does anyone know of any alternative hubs / flanges that will fit a 4HA axle? Mine currently has 4 x 4.5" PCD but I would like rear hubs drilled to 4 x 108 AND 4 x 100 to match the front hubs. This then gives me more flexibility with wheel choice.
If there's a hub to suit that is already either 4 x 100 or 108, then I can have the other pattern drilled. Alternatively, if there is a blank hub available, I will have both patterns drilled.
Also, is there a replacement non watts linkage diff cover available to fit, as the cast ally one on mine is cracked and beyond repair. I'm not 100% sure what I'm looking for to be honest, whether I look for a 4HA diff cover or a Salisbury diff cover. I have read somewhere that a Land Rover diff cover will fit, but i'm a bit dubious.
Thanks guys
Dave

Hi, Salisbury is the 'make' of the axle, 4HA is the type or size of the axle. Be aware Scimitar,s have different axles for different models, Se5 have 7HA and Se6 have 4HA for example. Land Rovers have 8HA. An XJS diff cover will fit the 4HA axle.

Thanks for the response. I knew that Salisbury was the 'brand' and so on, what I was meaning was if i'm searching for parts for this axle, what am I going to have most luck with. Searching for 4ha axle parts on ebay hasn't been so fruitful yet, and I wasn't entirely sure what else they were fitted to other than old jags ans Scimitars.
Mine is a 4HA off a Scimitar SE5a with a width of 54" which it seems is perfect for my HC Viva. I just need to have the brackets foe the Viva arms sorted, which is why I don't need the watts linkage parts. The axle never came with the watts linkage and the diff cover plate is knackered which is which I am after a non WL cover plate.

I think the flanges are unique to the Scimitar with the tapered shaft end. You're only option is to redrill, I'm not sure if there's anyone out there who'll be prepared to make a set of new flanges if you threw enough money at them? For the diff cover you'll want one from a Jaguar, the older stuff E-type upto the late XJS. They'll either be a plain pressed steel or finned cast aluminium. Forget anything you read about the Land Rover stuff being the same, from a distance they look similar, but up close they're enormous in comparison. A mate is doing the same conversion to his Viva with the SE5A axle, he's got a powerlock differential from a late XJS to go inside his axle with a minor mod

That's the plan with mine. i'll be breakin my mates' dad's Jag in a few weeks but i think that's got the dana stuff in it. it's a straight 6 XJ6 so I don't think that will be of any use, to me anyways.
My diff cover plate was the finned cast type and its really brittle and chipped and cracked everywhere. Steel is the way to go I think for my application
I'm going to drop my axle casing up at Ian Jemison in a few weeks as he has a jig to fit the viva brackets to the 4HA. I might ask him about hub flanges and see what he thinks

And I won't sit down. And I won't shut up. And most of all I will not grow up.

Just redrill em. Anyone remotely competent should be able to do it, it's a proper easy job, I did mine to 4x4" pcd on an axle for my stalled FC project. Sold the axle in the end, but I'd got it redrilled, narrowed, converted to 7/16" studs and 13" Vauxhall steels which id banded out bolted up.
