If I manage to get it all working I may attempt a write-up of the process and some details for future use.

I do have the assistance of a skilled machinist and mechanic - my aim is to gather as much relevant information for the task at hand. To my knowledge there are no companies doing conversion kits around here - so the general idea is to do everything by ourselves. I have searched the forums and the internet for information about the install and the modifications necessary, and found lots of good information. I also have the relevant drive shafts for the two, splined at the OD end and with the cam driving the oil pump of the ODs. The P-type is able to run a little bit higher pressure internally due to this - but I wouldn't expect a fairly stock fourbanger to be able to bring either even close to the limit of their capability The differences between the two are small - the P-type is slightly older and uses an asbestos friction material in the clutch, the P/J-type is newer and (therefore) uses an asbestos-free friction material. I already bought two overdrives, one Laycock P-type, and the other a Laycock P/J-type. In the on-going restoration of my 1931 Fordor I am currently looking into the possibility of adding a Laycock overdrive.
