That is interesting, isn't it Tom. I forget the date of the Service Letter and how late in the model year run it was. Also somewhat interesting that the first use was in the factory-reconditioned blocks and that came before the running change in production. And to make it more interesting, you wonder what prompted them to make the change as all the 34s I know of run the earlier style plate and I don't know of anyone who has problems attributable to the plate. Now problems with the oil cooler core is another story - there is a Service Letter about an improved design core but I don't know if I've ever seen one of those or not, nor how it differed from the first style. I went thru one leak of the original core (which was hell to clean up from, what with all that oil in the cooling system) and replaced my core with a length of finned flexible high pressure tubing. Pictures enclosed if I can find them.
