I ended up using an all trac 3sgte block in my mr2 a while back and am tired of burning my hands trying to get to how the All trac dipstick is mounted. I was wondering if there is any way I could swap in the MR2 style dipstick? All I know of the two is one uses an O-ring, and the other uses a compression fitting IIRC, and not sure if it could be done...
