I have been living in the Philippines for about 7 years now and naturally therefore developed an interest in the local assembled Camaros.
As you might know, all Yutivos were 6 cylinder 250 cui models with either a 3 speed manual (like mine) or the powerglide transmission, some say that all Yutivos were RS models. Almost all the Yutivos I have seen, has been modified to V8's (as you also can see on my website). In fact so far I only know of one other original drivetrain car - a white 67 standard coupe with black deluxe interior, but I am sure there are more out there.
Kurt S has the info on my car, only the rear end we did not yet get any numbers - hopefully when I come back to the Philippines by next month I will be able to get the numbers of the single leaf 10 bolt axle.
