I have been tearing apart my diff for a rebuild. I watched one excellent Dana 44 XKE rebuild video on youtube from 5speeds.com . In it the mechanic discussed the differences between an aggressive vs smooth clutch pack. Based on this I think I want to go with the smooth pack but don’t know how to identify between the two. BTW my diff is stamped 69 serial # N2039C . Any thoughts out there?? You can watch the video here:

Give Paul, whose video you watched, a call.
I’m sure he can source them for you.

Contact IWE Rear Ends Only. iwerearendsonly.ca. And discuss what you need. These guys have been doing jag differentials for 35 plus years.

I did contact him. He does not source the parts himself so didn’t have the specifics on the parts himself or where they sourced them. But he did get back to me with a recommendation to check DTS [Drive Line Specialists) which is actually near me so I have sent them an email.
Terry where are they located?
They are in Vancouver B.C.
When i was racing an E Type I’d change the clutch pack every two years. There is, what they call a “heavy duty” clutch pack with 2 dished plates per side - I believe the Dayna (Spicer) part no is 22937X, whereas the stock one is 22233X. This is available from this guy: https://www.dennysdriveshaft.com/p3680_dana_spicer_22233x_powr_lok_dana_44_positraction_clutch_plat.html
These diffs are typically Dayna (now called Spicer) 44’s manufactured by Salisbury etc, and are very common in just about every car manufactured, though there can be differences internally. For example the number of splines that the discs have to mate with the output shaft can differ, so when you buy for an e Type you need to be careful. You can always talk to a 4 X 4 repair shop about these diffs. as well as they work on Dayna 44’s all the time. The center sections of many are very similar, while the output shafts can be very difficult to non existent on a solid axle .

So I’m having trouble identifying what this rear end really is. The car is a 70 number IR- 1026 and the casing is stamped 69 serial number N 2039 C which would indicate its a type 2 diff. . HOWEVER… the output shaft assemblies are bolted directly to the casing , and which I have removed, clearly appear to be Type 3 stubby single bearing hubs. The type 3 were only supposed to be from IR-1244 forward.
The only difference I can see in the pinion shaft assembly from the 2 and 3 types appears to be the size of the Inner Bearing cup width of .9375 vs .9063 so this afternoon I will be removing and measuring it.
Stay tuned for an update .
John,
I’m confused by the car number 1R1026 (and later 1R1244) you are quoting. Both these numbers are for RHD OTSs. 1R1026 is a very early RHD S2 built in late 1968, whilst 1R1244 would have been build in Aug 1969 so on the cusp of being a 1970 Model Year car. Is your car 1R11026 perhaps? That would make it a LHD OTS built in Oct 1969 and therefore an early MY 1970 car? As you indicated, the records show that the Type 3 diff was installed from 1R1244 for the RHD OTS, and 1R9930 for the LHD OTS, so 1R11026 would have the Type 3.

Just so happens as we speak I just rechecked my car number plate before your post and found I had missed a digit in my records for the car number. The car is actually 1R 12026 so indeed it should be a type 3. The 1R 1026 number was in a response to me this morning from Martin Robey whom I had asked for help a couple days ago. Makes sense that the number is much lower as most of the cars were exported to LHD countries and although I was inquiring regarding an order to ship to the US they probably missed that and thought it was for the UK. So that’s solved but curious why the diff casing would be stamped with a C suffix which is what originally had me baffled.?. According to my Heritage trust cert the car was built December 17 1969.
The Series 2 RHD OTS car numbers started at 1R1000. The LHD numbers started at 1R7500. Your car’s number of 1R12026 is consistent with the December 1969 build date. I’m not aware of what the “C” suffix to the diff serial number means. I can only say that my Series 2 which was built prior to the supposed change to the Type 3 diff, also has a Type 3 diff with a “C” suffix to the diff serial number. Maybe my diff was exchanged at some point.

The C suffix is still a bit baffling but since the books say cars from 1R 9930 forward had type 3 and this car is 1R 12026 you would assume ts a type 3 especially since all the drive shaft assembly and fitting to the case is definitely type 3 . It did however strike me also at one point prior to this someone had done a refit of some sort.
Thanks for your expert input as always!
