What does that mean?

"The alignment pins between the engine and transmission may be missing."

Very good idea. Misaligned components would play hell with parts reliability.

I'm sorry for the spelling English is my second language and English is hard to spell

That is quite alright. We can normally figure it out. Good for you to have a second language. I only know English.

God I hope it's just a flywheel

Have you tried a forum for your car? The members may be aware of a specific issue that affects the clutch.

Yeah I am a active member on infamousnissan,not on as often now that I am no longer riding In a slammed straight piped 4 banger covered In grafiti trying my best to blow it up in pursuit or every last drop of power. They really let me down a while ago and I just kinda wrote it off. Here lately I have been a bit overwhelmed and the truck is low priority.

Hang in there. Things have a habit of working out. We all just want things to work out sooner and cost free if possible.

I think I may just put 20 pounds of thermite under it and take pot shots until blastoff

A drum full of oxy-acetylene works well too.
