so I removed the input shaft and the new TC seated right. I measured and the new and old shaft are the same length. but i put them in the new TC and the old one sticks n the TC an 1/8" more and then I did the same in the Trans and the new one sticks out 1/16" more. so thats 3/16" of an inch which is exactly how much I'm off. so I put the old shaft in the trans and worked it and I got the new TC to seat 1/8" below a straight edge across the face of the bell housing. so maybe the whole issue all along was the input shaft. Ill wait to talk to racer X, but I think Ill just go back with my old input shaft

well its back and running. old shaft new TC. no vibrations. just kind of worried about leaving monday for a 1600 frip into Canada. Ill drive it the next few days and see if any thing comes up. I imagine of there was an internal issue with my install I might no relatively fast.
thanks for the help, hopefully no Canadian emergencies lol

sorry for the delay... Just got back from the trip!
So my trip was 2934 miles. I did notice some things that had me worried quit a bit while I was 18 hrs form home in french speaking part of Canada where the high ways end and ferrys begin :grin:
I have a new distinct vibration at 20 to 25 mph
I also have a rumble at 55. Not like before though.
and also while sitting at idle I have an intermittent pulsing vibration
when the trans was out I also;
replaced rear drive shaft U-joints (spicer 5-1410X)
diff fluid front and back (amsoil synthetic and friction modifier)
Transfer case fluid (Schaeffers all trans supreme)
Installed Diesel site cooler line bypass kit
New internal filter
new external filter (for dieselsite external filter)
new fluid (schaeffers all trans supreme)
grease both slip yokes
I also tried to replace the the front shaft u joints, but i couldn't get the strap bolts off so I didnt get them quite yet, I just bolted it back up after greasing the slip yoke. I do know that it isn't in the same location on the flange though. I've read it doesn't matter, i've read it does. I don't know. I'll prob put it back. I would have anyway just to be sure but I accidentally rotated it and said screw it I was in a pinch for time and i was on the 4th bolt before I realized it.
I've read the tensioner and the fan clutch can cause some vibrations at idle, so I may just swap both. Also My tires being balanced kinda concerns me too, that will cause def vibrations at certain speeds as we all know. But all the driveline vibrations are driving me insane especially when It could be trans related...
My trans has a Factory tech valve body since 56 k and the external filter since 61 miles. I also wired up a TC lock up switch per Guzzles 7.3 write up.
The pump concerns me tbh. I may pull it again in the spring and do a pump from racer X also, and get the billet input shaft to fit when I have more time. I just know the pump requires some special alignment or something. Possibly also a billet flexplate
