I am looking for a XK120 Salsbury Crown & Pinion Gear. Can any one assist
Welcome Andrew.
We need to know which type you have.
If it is the type 4HA then the Dana 44 as still used in Jeeps uses many of the same parts.
If it is the type 2HA it was used in Studebakers in the early '50s so you could look for those but you may be out of luck.

If it’s a 2HA, you will need to define just what ratios you would accept. The 2HA and its American counterpart, the Dana/Spicer model 41, are relics of the 1940’s, when road speeds were much lower. Gear ratios were typically much higher then (4.10, 4.27, 4.56, etc), so the 3.54 or 3.77 you would find in an XK 120 of the same era is really an exception rather than the rule.
The country you are located in will have some bearing on what is readily available.
to identify…if you are not sure of 2HA, 4HA, post numbers you have, photos of the casing of the differential…any numbers, markings you find on it…and photos of the raised hump on the rearmost of the differential…thick or thin hump.

I am looking for a 2HA Salsibury.
The ratio that I am looking or is 3.77. However a 3.54 would also be great. It is to be connected to a SS 3.5L Engine.
Is this for a pre-war SS model, or an XK? If it’s an XK, it’s easier to swap in a later 4HA than find usable 2HA gear sets.
Andrew, just so you know, there is a dedicated forum for selling and wanted items. Unfortunately there is a requirement that needs to be met before new members are allowed to post.
The forum has rules regarding posting in the type specific forums.
The differential housing is from a MK4. I am not familiar with the full techical details of these housing and compatibility and would appreachiate advise.
The challenge is that the Salisbury 2HA and it’s Dana 41 counterpart were out of production by 1953. On the other hand, the Salisbury 4HA and Dana 44 are still made today. It is entirely possible to have and entirely new bespoke Dana 44 rear axle made from off the shelf parts. Not so for the 2HA. Very challenging to find ring and pinion sets, not impossible, but challenging, in the 3.xx series. 4.xx ratios are much more common.
Your profile says you have an SS100, but they originally had ENV axles.
A Salisbury from a Mark IV looks like this.
They would have been wider track at 56" than an SS100 at 54".
It may be yours has been converted, or your car was made out of a donor Mark IV.
In any case, you want the pre-xk forum where there is more knowledge of the earlier models.
I am building a SS100 Clone, completed around a 1939 M series SS 3.5 Engine and a scratch built SS100 chassis. Most of the work was done a few decades ago. The differential is a MK4 2Ha diff. Interesting is that the differential has differnet shocker fittings than the exploded drawings above .
I’d swap in a 4HA and avoid the headache. You can get any ratio in a 4HA. Limited slip is no problem. It took me 10 years to find a usable 2HA ring and pinion in a 3.xx ratio.

I am after crown an pinion, XK120 3.77 Ration Salisbury. Does anyone have a set.
Andrew.
Place a wanted ad in the classifieds section.
Andrew you have a much greater chance of finding this item in this section as this is where XK owners go.
The 3.77 ratio is a very popular ratio in early 2HA Salisbury diffs in American cars.
There is one on Ebay now. JAGUAR XK120 3.77:1 USED CROWN WHEEL + PINION 13/49 SALISBURY 2HA JAG #3889 | eBay
and this is how the XK forum works

It might be prudent to remember that the owners of J-L set the rules, and they insist on wanted and for sale postings be restricted to the Classifieds and there are potential consequences for ignoring it.

Nicholas,
Thank you for clarrifying this issue.
Ed Nantes indicated that this forum was the best to assist in my looking for the differential parts.
