Re: Buying alfa
Later Suds and Sprint had a second pair fo holes for the seats so those from a 33 and perhaps an alfetta will bolt straight in as you did.
As for spark plugs , as most here agree, will not do any difference in performance so stick to the cheapest.
On the first change just check the water tappets on the engine motor because they tend to rust and you dont want to loose all your water far from home. Tehy are easily ti replace and from what i remember they must be 12.
