Hello friends of the Alteneisen 🙂 , Does anyone have any idea if my conversion still conforms to H-marks? My project: I own an Opel record D from 1977 with a 1.9 liter (75kw) which is still under construction and would like to install another engine from the Commodore B GS/E i.e. a 6-cylinder with max. 125 kW (that’s enough). I know that according to the conversion catalog at that time the data are only in KW and that I then need their axles ( 5-hole) for the engine. on an H-mark? Background of the motorization is that I want to move a caravan for various WE-meetings also for the surrounding abroad, to stay in the tent is no longer my thing. Thanks for a quick helpful answer.
