Help! Replacing the hydrobooster on the 81 Euro with the P37 chassis and the 350 engine. The rebuilder of choice is Cardone who lists one unit for this application but it is not available. Sent the old one to them and they rebuilt it. Went back to Cardone and asked why the 81 has one booster but the 79 and 80 and 82 have three compatible units that are in stock. No good answer so I ordered one to see what the difference is. Always want spares on old vehicles. Now trying to replace all the hoses but guess what - six different ones come up. So far two do not fit. Asking if anyone has a part number of this hose. Thanks

I did my 86 a while back. good luck, I ended up making one line myself. Not sure if the 350 is set up same as the 454. See here:
