Thats a good question. I'm not sure where you could look it up. I'll do some research and get back to you. I have some old body and frame measuring books I can look thru. Talk to you soon
There you can measure from the front bolt back 44.85 to that measurement point but honestly right now the jackstand might be in the way of that that.
I don't have another car around to even check it to see if it's plausible. If I wasn't so beat down old and tired I'd just go ahead and bolt the engine snug to the k-frame and pick it up, and start backing bolts out. But man I really don't want to go through all that and then find out that they're all that way so what would be really helpful is to know if other cars measure out equal at that point or not.
Between you and me, I'm pretty sure the way things got better when I swung the tailshaft against the passenger side of the hump is telling me the truth. The crossmember is located parallel to the frame rails. The transmission was out of position when the crossmember was bolted in. I can't move the crossmember. I can move the k-frame. But I also don't know if the car has ever been hit either. It doesn't look like it, but I don't know after all these years.
Also, the difference in the measurement, if changed to be equal, seems like it would rotate things the right way (tailshaft toward the center/driver side).
Tell me I'm wrong before I take on this task to find out it wasn't necessary. :thumbsup:
