Yes it will fit BUT... You'll need to move the drive pulley to compensate for the difference between the manual PTO (on the 108) and the electric PTO
(on 1650). Be VERY CAREFUL when doing so as not to chip or break the drive pulley or damage the input shaft on the right angle box!!!
Use lots of PB Blaster and let it soak in.
