I'm thinking of reconditioning an EK gear box from a grey motor then do a swap into my FC Ute.
My question is are EK gear boxes the same as FC gear boxes? Can a straight swap be done?
Or am I better off getting my FC box reconditioned and have my FC laid up for a week?

Kevin,
There are three separate grey motor crashboxes - early humpy, FJ-EK and EJ, each of which is different to the red crashbox. I suspect they are largely interchangeable, perhaps with the exception of the EJ grey box.
Case assemblies changed between 48-FJ and FJ-EK, though I suspect the changes were minor. EJ and EH had the same case up till EH engine number 81520, then EH-HR got it's own case. Extension housings were identical 48-EK, EJ got it's own housing, as did till EH engine number 81520, then EH-HR got it's own extension housing. There were also internals changes as well.
Short answer is I believe the EK box will be a bolt in for the ute.
Cheers,
Harv.
THE EK box does in fact bolt straight up as Harv says, but it had important internal changes which make it superior - the most notable are double row ball bearings on the main shaft. Given a choice, use the EK box.

Many thanks Harv & Ken, I'll go with the EK box then and keep the FC one for a spare. ;D
