I "think" the rack came from an '80 240, the place below shows 3 different ZF racks.
Type I, II and III

Thanks
from my Jan 1994 "Quick Reference Parts Catalogue" there *are*
three ZF units listed *and* the kits "from Volvo" that match
ZF rack marked 1229394 ................ gets kit # 1272537-0
ZF rack marked 1272984 or 1329694 gets kit # 1273576-7
ZF rack marked 1329694 ................ gets kit # 271562-1
and *yes* I *know* there is a "cross over" between the second and third
racks that will require a discussion w/the "parts guy" at your supplier (he
*should provide* the discriminator ) for you to get the correct kit...
too bad you don't have the "hulk" to refer to...the *BUILD PLATE* has that
info on it! which in THIS PARTICULAR CASE is *IRRELEVANT* because
it only identifies the MAKE by number and *not* the TYPE of ZF rack!
the "production date" may also guide you w/clues...buuuut.....
yer gonna have to go w/what you can find on the rack itself...
my VADIS reference is not on site yet so I'm going "old school" here
there *might be* someone lurking that has the PARTS FISCHE that
may have more info but IIRC you *always end up AT THE RACK*
looking for numbers...
