Hi Steve, Beware the rubber (neoprene gasket) I tried these gaskets but each time they sprung a leak within a couple of weeks, the second one, when I had to remove it, it had split quite badly between the bolt holes on the rear flange!, I don't know if there was a reaction with the fluid but the split was extensive, I hadn't tightened the bolts too much so no problem there, I then went back to the cork type but as Harvey says, it is paramount to level the pan flange, I spent almost 2 hours getting this level so now there is no leak from the flange, however, being a type 35 there will always be a leak from somewhere! Good luck
