rocker alignment

[johnnydog]

I've been rummaging through my spares, and it would appear that nos rocker arms part nos 109023 / 109024 have a oil hole on the top above the shaft, whereas 139896 / 139897 don't. I presume one superceeded the other? Looking at my used rockershafts, it seems there are two types, the main difference being the end pedestaI and the method of retaining the rockers etc on the shaft (one type has a mere split pin, the other has what I would describe as a 'cap'). I presume they are interchangable on the engines as a complete unit?

Yes, I would have thought that they were interchangable as well, and I noticed the difference in the rockers , all the newer stocks on offer have the oil drilling on the top.
I took some measurements at Rimmers request and it does look as if there is a dimensional difference affecting the amount of offset between the old and new parts.
I have left it with Rimmers now, telling them that I'm fitting the new parts anyway suitably shimmed into position on the shaft as best I can, as I really want to have the car back on the road
