Re: 88 2.9 auto 2 manual
i am not sure about the front shaft but i think the front shaft from a 4x4 is smaller than the rear shaft which would probably not be strong enough and i still think the length would be wrong. i think you need a driveshaft from a standard trans truck or you can have a driveshaft custom fitted which might be salty $,$$$.
i am sure you could weld something together yourself but it wouldnt work right. it needs to be balanced or it will vibrate real bad and probably eat u-joints.
i would rather push my Ford than drive your Chevy !
