Well i am still alive here. I have started my RY but i am using the alt parts.I seem to have run into a problem that i hope someone can help me with.I have built the first 10 pcs.nose,NL,BL 1,2,3,4,5,bridge,and BSU L/R.I used the alt parts NL,BL2,bridge,and BSU L/R.As i started to assembly them they will not line up on the BSU sections.There is a gap between BL1,and BL2, and BL4&5 wont fit on the slope they end up about a 1/4" past onto the flat part.It appears either BL2 is too long or BSU is too short.Anyone have any idea how i messed this up?Pics r forth coming.wall1
