Idunno about best, but the only one I ever did was a 65 Valiant wagon, and I used fenderwells.Back in about 74, that's all I could get. Wasn't the best for front tire clearance, but back then I was a point and shoot kinda guy. I'd do it again,if I got the chance.
Modern, under-chassis/over steering, are pretty tight in 67 up engine bays;never mind in the early A's.
