Thanks Rob, yes to the question both sets were worn beyond spec. I was thinking of making up some shims to put in behind the washers if I can't get new ones.

Thanks again.

I have had another look at the date casting and agree it is more likely H36. Thanks for all the feedback, so when I re-build the box for my 57 FE I will use the two long rib extension. Can anyone suggest where I can get my hands on a set of new thrust washers?

Thanks for the info, from Harv's photo the housing on the left (two long webs) is the type I have with the metal (tin) guard mounted on the larger rear boss. My example of this housing came from a box with serial number L409584 and a casting date of L 47 ( 04 Nov 57) and in addition to the cast part number and  HOLDEN the number 21. My other housing (centre housing in photo) came from a box with serial number L293376 and a casting date of H 38 (I assume from the early in the run serial number to be 03 Aug 48) with the additional cast number of 92. My questions are, do the additional numbers indicate different manufacturing locations or just different molds and could the housings have been used in different assembly plants or on different models i.e. utes and panelvans?

I have two crash boxes both FE going by the numbers, L293376 and L409584, but with different rear extension housings. One has four short webs at 90 degrees to each other, the other has only two long webs one on either side extending the full length of the housing and a metal guard over the seal boss. Both housings have the same part number, 7408348. My question is, did boxes fitted to commercial vehicles get a different extension housing or did the housings change at some point i.e. FJ to FE?
