ok,, can you tell which ones are which... are they colour coded.. ie .. red 
is light duty,, green is heavy duty...
are they thicker,,,, ?   more on that copied below....

My 74 Bay Westfalia seems to weigh in at 990kg on each axle.... so it 
doesn't really seem rear-heavy...
also I noted ...
if you put a floor jack under a trailer hitch on a "saggy" bus.. and lift 
... you will see the entire bus rise until you top out the rear suspension,, 
then only the rear will lift..
seems that torsion bars sort of equalize the weight???

ok,, back to the  topic of heavy duty torsion bars..

a while back , you [Accessys at smart.net] mentioned

and I have a spare pair of green torsion bars.. iirc.. they came out of a 78
camper that I parted out. they measure 29mm x 610mm

I would think the 3mm larger ones might be heavy duty...???

the VW parts book lists 4 different torsion bars. the green bars are
heavy duty, as they are listed as being for M140 (fire truck) and
M531 (hard torsion bar). there seems to be 2 different green bars
however and i can't say how you would tell them apart if the numbers
were not on them.

according to the book, since a camper was built on a type 231, your
'74 should have 211 511 115 C and 116 C, which are green bars and
heavier duty.

i can't say for sure if the bars from a '78 are the same as '74 since
the parts book technically ends at '72. we have a '78 7-passenger bus
here with the rear suspension taken apart and it has red-brown
torsion bars, which also agrees with my parts book info.

the photo with the two bars that are different lengths doesn't make
any sense to me. they are the same length.
