Seat Back Query CP10/SB4??

[rpjg1975]

Having built up the seat back a while ago, I have now got all my chassis plates and found that the CP10's don't fit where they should?

According to the book diagrams they seem to be positioned at rear edge of each SB4 but when I measure the length of SB4 they are too short. Looking at the book SB4 is 269mm at the front edge and the CP10's are 268mm long which is too long to go at the back. Obviously they would fit at the front but that isn't what I can see has to be done.

Is it just a case of altering the length of the CP10's to fit or am I missing something? Chassis kit came from Armoto and Chassis plates from 3Ge and all seem to be correct sizes so I am a little foxed!!

Help!!!
