My 40 year old allow rocker cover is not sealing properly any more. It still looks good but years of tightening up the bolts has resulted in all the bolt points dishing out and being alloy, will most likely crack if I try to straighten out. Not sure what to replace it with. What have some of you folk used on your holden 6? Anyone used one of these Aussiespeed covers? Any drama's, did you need a thermo spacer? The cover I have now is similar to a Kilkenny KC210P (probably the same thing). Any opinions, I don't really like all the welding marks on those fabricated ones.
