fedral mogal are good though...dont worry about price..whats done is done..
may i recomend AUTOPOST..in croydon...ask for Paolo..(might av spelt that wrong, pronounced pall-low)...he is good...knows his stuff, parts are cheap..ask for genuine or OE..they have (he does asnyway) no quibble warrenty, always excellent service..
do not speak with older lady or gent..only paolo!!!(cos older gent is rude, and older lady knows feck all)
ignore their website ..it is crap..just ring them..NO PAOLO =NO ORDER..
i have rebuilt my 4.6 using thier parts.(and turners).perfect fit..20psi oil on cranking (starter only) using their OE tappets,rockers (steel ones) and shafts..these he uses himself..
otherwise..turners..real steel......not rimmers..not paddocks...people on phone are sales only..no knowledge..(though parts are ok..)
