Pel Job Y12

Hi There Newbie here. Got Pel Job Y12 1988ish. Need the alloy valve block that is under the drivers left foot. Cant add a picture for some reason. It says on it, Oil control Modena Italy Brevettato 057146370235000 VAA B S1C 50 38 PDRM 35 1/9 Anybody got one lying around? The alloy is cracked between 2 ports so a bit hard to do a repair. Thanks in advance for any help or advice. Tom
