This is for a ‘64 stamped 1F (f135). Don’t know if the hole sizes are different over the years, but I‘m looking for one with the PCV boss. I have one without the boss. There are’t any hold down bolts or such at the block on this motor, just the strap/bracket thingy on the upper part of the tube that bolts to the lifter cover. If you have PCV valve too I’ll take that, I think they’re still available from Toyota?
