JPOR: Re: jefe's new D60 with a twist

["Randy Peterson" <rkpete@xxxxxxxxxxxxxx>]

jefe,
I plum bobbed my cj years ago and found that the centerline of the crank does not line
up with the centerline fo the frame. I think CJ7 factory stock straight six are not
centered or square with the frame.

Do you think that the dana 44 in the front will hold up with 44" tires ?
