Thanks Norm for putting things straight! your information is really a good pointer in the right direction.
My 1929 D60 Touring is visible in the 'photographs section' of this website; and is actually a first series sept 1928 Leaside built D60 Touring.
That means that according to your info the smaller CU/size L14 engine has been used.
The piston dimensions which you have stated are of great help; as the bore diameter is still 2-7/8 ; these piston dimensions should also be suitable for my 'smaller'CU L14 engine...
@ Rick: thanks for sharing your experience with this Australian firm; I'll drop them a line.
Ah checking Steve's Registry I see T-4067 with 14L 119390 which was Oct 1928 to Dec 31 1928 T-1001 to T-5000. so series 60-1 but vin wise is 1929 model year. So per Chilton yours is the bigger DL195 with the engine after 93324. DL43 Smaller piston is 2 3/4 pin is .734
Nothing simple with Billy's vehicles with things not all happening at same time. Such as the 14L small / big both 60-1 series. See it in Durant aftermarkets, to a certain vin and after on same model. Just adds to the confusion when parts get changed over the years as to what was orig used and why we have problems replacing things.
