help needed with the R143 subway car by jaleel King

[mity22]

I have posted on the general trainz forums but got no help I think this is the better place anyway. This model has a error that I cannot fix? 2 Kuid,s CMP says are not in the database and could not be found in any known location the others are numerous errors like attach point "103" must be found in mesh. Could someone please help or offer any insight as this has really got me stuck. :'(
