 Ditto, here. I don't think it's a problem, though. European 2 liter buses
 got the hydraulic lifters in '78 and kept the twin solex carbs.

 '76 and later buses have the 228 mm clutch, should be no problem as regards
 the cable. I'd get the pressure plate and clutch that goes with the flywheel.
 You might call a VW transmission rebuilder just to make sure that the input
 shaft on the transmission in your '73 has the same splines as the later 
 buses. OR, you may want to get an 091 gearbox from a 2 liter bus - They have
 way more ribbing on the case, there may have been some changes to accomodate
 the added torque from the 2 liter engine.
