On the other issue raised by Alex...... in the Chev parts manual dated Jan 1941 they list the cowl as a separate part from the ARCH BARS...... and the cowl is common to all sizes of cab11/12...... on the other hand they also list the ARCH BARS right and left ( confusing because to us restorer they are all the same once welded to the cowl angle iron) and shows that the arch bars are all the same part number for RH and LH for all C15, 15a,30, etc. size trucks....BUT the C8 has a separate part number which would reflect it own peculiar BAR shape due to the different frame, steering configuration, etc.
I have two sets of C15a spare arches at the barn ....... I could not find any numbering on them at all.... mind you all are rusty.

Phil, Bob, once again thanks for all your comments and ideas regarding the arch bars. And what a coincidence that you were right in the middle of arch bar replacement, Phil!!
My main question was how to tell a C8 arch bar assembly (trying to find a suitable name here for the weld assembly of the three parts....) apart from a C15A one....or a Ford one for that matter. As usual such a question results in an interesting query.....with new questions arising along the way....what's the difference between Ford and Chev?. Is there a difference between cab 11 and 12......what's the difference between the C8 and other Chevs?
My intention was to find out if the arch bar assembly in the yard at LWD parts was from a C8.... and possibly a suitable replacement for mine...which is pretty rusted. Dirk and Stefan were very helpful as always and it was enjoyable to talk about the hobby. Sadly for me the assembly they had available proved to be from a Ford, so I have decided to try and repair my rusted example.
Maybe this info is useful for others, otherwise it might be the dullest info ever posted
- Ford vs Chev Arch bars....the Chev RH arch bar has an extra bend/bulge, to give some extra space for the pedals. I guess Ford's don't need the extra clearance (?), as they lack the extra bend.
- The cowl as mentioned by Bob is listed in the Chev parts list with a Chev part number, as well as a Ford number, so I presume the cowl is the same for all(?). I don't have a Ford parts list here, so I can't check if all Fords used the same....nor can I check if the F8 used different arch bars (compared with F15 F30 etc.) as seems the case with Chev.
- I have to check Phils pictures closely, but the parts list seems to suggest the cowl is the same for the cab11 and 12. Usually there is a mention of "before serial...." if there is a part difference between Cab 11 and 12....or a mention on using up old stock, before using the new part(number), but that doesn't seem to be the case here.
- Also interesting.....in the Chev parts list you will notice that it takes 2 bolts and nuts less to assembly the fenders on a C8, compared with it's bigger brothers......so, could that be a way to tell a C8 arch bar assy from the others?
- The fender itself are definitely different in width between a C8 and the sisters....we compared my C8 fender to a fender of the F60H....wow....a considerable difference!
Phil, please keep the pics of your work coming....never dull....always useful! good luck with the engine.
