steering u-joint question

[chip46wis]

Ok,I finally got back to my 69 step after 4 months.I have a tilt column from a chev van-keyless type,upon installing it was too short by about 15 inches,I found a intermediate shaft from a newer chev truck which I can cut down to length.
My situation is this---the intermediate shaft has a DD type shaft-the end of the steering column is a splined shaft 36? spline? I called a well known steering specialist company and of course we need the measurements for the shaft , I come up with a 11/16 on each end, splined and DD ends. is this really a 3/4 that will clamp down?
I see speedwaymotors offers a 3/4 DD to a 36 spline 3/4 weld on type u joint,anyone ever do this or any positive input on this? I assume it also has a method of clamping. (I am a certified pipe welder with a tig setup)
Any help appreciated--- Chip

measure the shaft at its widest point. The standard is 3/4DD and or 3/4 36 on the lower column end spline. But again measure the column shaft at its widest not on the spline. I think Unisteer will have the joint you need. You shouldn't need to weld the joint inplace.

Check www.borgeson.com . They should have what you need .Be safe when doing steering .

some guys take the original intermediate shaft and drill the sheer pins out, then you can collapse it to fit... this is also how some guys move their original columns closer to the dash for more "belly room" behind the wheel...

yeah, the shaft originally on your truck will work.
