haha, took me an hour to get it aligned on my jeep. Just play with it and dont get fed up. It will line up sooner or later

Did you use an alignment dowel to keep the clutch disk spline in line with the pilot bearing (Edit: when you bolted the pressure plate to the flywheel)? (They make a special tool for this. I have made them out of wood before. I have been known to use an input shaft for this as well.) If you are getting that close it sounds like you are getting the input shaft splines in the clutch disk but not getting the shaft started in the pilot bearing. You may need to loosen the pressure plate and re-center the clutch disk. If the gap is larger than you reported then you may not be getting the splines aligned between the input shaft and the clutch disk. In which case you may be able to put the transmission in gear (fourth is a good gear for this) and rotate the output shaft (which rotates the input shaft) to get the splines to mate.

If you have the alignment tool, make sure it is free in and out, if its off slightly, it won't go together.

Be sure the bushing is lined up and that it wasnt damaged when you pulled the trans. Then grab two new bolts that are longer than the stock trans to bell bolts. Cut the heads off and then round the edges. Cut a grove across the cut end so that you can get it back out with just a screwdriver. Now install these two bolts in the more acessible holes. The headless bolts will act as a guide so you dont have to juggle the trans as you line things up. Once you get two of the real bolts snugged up, take the headless ones out 1 at a time and drop in the real bolts.... Thanks to my Dad for that trick.... Chris

1. Alignment tool = critical.
2. Carefull handling of transmission, do not let it hang!
3. Alignment pins for trans, good idea, I use them also.
4. Put it in gear and wiggle the output splines as you manuver the trans into position.
5. Start over, check the disc on the input shaft splines from both directions. If you have a minor burr, you can touch it up with a file, no problem.

If you start over, check for those small dowel sleeves on each side of the adaptor plate, these align the centerlines, very important parts.

DO NOT use bolts to force it in, only causes problems, bent disc, possibly even drives the pilot out the back of the F/W, yep, fixed one of those already.

Patience and skill, not force.

Good luck.
