Modified bottom frame
A - holes with a diameter of 6.0 mm, B - body stiffeners
Since November 1988, new bolts have been used to secure the rear of the lower frame. Since mid-1992, the installation of the rear of the lower frame has changed. The rear bolts have been increased in size from M12 to M14. Bottom frames with M14 bolts can be identified by the presence of 6.0mm holes located behind the rear units.
