Rear shock absorber casing mounting

I have bought a Series 2 LI 125 engine and I have noticed that when I fitted it to my scoot, the rear shock mounting on the casing protrudes 53mm. This means that there is a gap of about 5-6mm when I fit the rear shock! I measured the rear engine mounting on the casing of my GP200 engine and it protrudes 47mm and there is no gap when the rear shock
Is fitted, so it fits perfect!
Is this normal for the rear shock casing mounting on a series 2 to protrude this distance and have this gap? I suppose I will have to shim the gap with washers? Or any other ideas folks????
Cheers
