I've been concerned about the quality of some of the unbranded bearings being sold for diff and gearbox rebuilds, so I tracked down equivalent part numbers and sourced mine from reputable bearing factors. These are based on the Triumph part numbers for my Spitfire 1500 with 3.63:1 ratio. BTB440 - pinion outer. (Listed as an alternative to 134070) Timken Part Number M84548 - M84510 1”x2.25 (2 ¼)x0.765 (49/64”) 134065 - pinion inner Timken Part Number M88040 - M88010 1.1250” (1 ⅛”) x 2.6875 (2 11/16) x 0.8750” (7/8) 28.575mm x 68.263mm x 22.225 Diff Carrier GHB105 - diff carrier (to commission number FH106101 equiv. to UKC169?) LM67048 - LM67010 (TBC!) (31.75x59.13x15.88mm) UKC4805 - diff carrier (from commission number FH106102) Timken Part Number L68149 - L68110 (TIMKEN set-13? might be the same, it has the same dimensions?) 1.3775“ x 2.3280” x 0.6250” (34.99x59.13x15.88mm) Not as hard to find, but included for reference: 533360A/128572 Inner axle shaft (output shaft) bearing bearing part number 6205 C3 clearance 25 x 52 x 15mm Please treat with caution! I'm in the middle of rebuilding my Spit diff with the bearings listed above, everything seems to fit just fine, but there's a chance I made a mistake! Updated again based on some more research - I'll try and confirm more ASAP

Hi to all. What a great site...just for people like me who know better than the engineers with their big budgets that design, develop, test, refine etc...What do they know??? So, I fitted a tuned 3.5V8 and a LT77 box to my '77 Triumph 2500S, owned since 1981. It is such a pleasure, great accel, blows a lot of guys off the road and comes back for more. However...the differential kind of "snaps" now and then. I am in South Africa, and 2nd hand 3.45:1 units are getting very scarce. Please could I have some practical suggestions to strenghten the rear. I would prefer to keep the ratio as close as possible to 3.45, or slightly higher, maybe up to a 3.08. Of course LSD will be lovely too.I am not the first person who has done this to a Triumph/ I would like to keep the weight down, so I want to veer away from a Jaguar unit. I am open to suggestions. Please help. Thank you Johan van Wyk
