Anyone with experience on a saginaw 4spd swap into a lwb truck? I pulled an sm420 out and rebuilt and installed the 4spd. Now I need to modify the foward driveshaft but once its done all that'll stop the front shaft from walking fore & aft will be the hangar bearing. A one piece probably won't work because my 62 frame is an "X" with a small tunnel in the middle and could rub the shaft at the suspension limits. Like to hear from more of you on a single 2bbl weber for a 261 too. Thanks
