hey guys, today i was contacted by a fella with the same issue as i have with my intermediate shaft that is too long after newer bell housing and engine swap. the issue is that the engine coupler stops at the end of the splines prior to the engine seating up to the bell housing . now after contacting a large list of machine shops i finally found one to help but am faced with two options as follows ..1) pay them to purchase correct cutting tool and cut the splines deeper onto the shaft allowing the engine to seat up with the bell housing or ..2) they can make a relief cut on the shaft behind the splines allowing the coupler to slide further down the shaft and the engine to seat up with the bell housing but , this will decrease the spline contact between the shaft and coupler.... now the intermediate shaft splines would still have about 7/8 " to 1 1/8" contact with the coupler. if anyone is still following along after all that the question being...option 2 is WAY cheaper than option 1 . is 7/8" to 1 1/8" contact enough ? thanx in advance...dimitri
 
I wouldn't do option 2 behind a V8...maybe ok for a 4 cylinder.

I don't understand why they wouldn't put the shaft in a lathe, cut the length out and weld it back together

You need to find a better machine shop

I would cut the shaft to remove excess length, drill both ends, insert a dowel and weld- penetrating the dowel and the shaft. Fill with weld.
Then, I would grind the excess weld off, slide a sleeve over the connection, and weld both ends of the sleeve to the shaft
 
what happens if you just pop the plug out of the front side of the coupler?
would that not let the shaft slide in further? into the recess of the engine crank?
