I did mis-remember just a bit, the capacity it was 2400 kg! Here's a pic of the hitch installation info"



I didn't take any pictures of the 126 hitch; it was the same basic system though. The bar across the back behind the bumper was twice the size if the 123 hitches I have, about 4-5" high and 2" wide of very heavy steel rectangular box channel, plates on both ends which used the two vertically arranged bolts as attachment points. On this hitch the factory two bolt/plate setup was removed and there was a heavy stamped steel sort of L shaped bracket which had two holes that lined up with the holes in the chassis through which two heavier bolts where used to sandwich the chassis sheet in the rear bumper mount area metal between the bumper on the outside and this bracket on the inside. These brackets where bolted vertically in three places along their bottom edge into the channel at the bottom of the frame's box channel in the space behind the wheel well. The where two bolts that went through the bracket's up-right face, these bolts passed through the bracket, the chassis sheet metal, and through exterior underside heavy steel straps that attached at the other end to the bottom edge of the hitch's main box channel.

The fellow I gave this to intended to weld a 2" receiver to the bottom of the main steel box channel, along with some appropriate reinforcement. The main channel box was very heavy duty and weighed probably 75+ pounds, the stamped steel brackets where also heavy duty steel probably 3 maybe even 4 mm thick and formed in such a way that the main section was "L" shaped but had a 1" deep lip completely encircling the "L". It was an extremely strong and rigid design. The exterior underside straps where also quite thick about 1 1/4" wide maybe 5 or 6 mm thick, they had a 90 degree twist to allow attachment on the flat side to the horizontal bumper main channel box and the other end to the vertical side of the interior bracket. These straps also where attached inboard of the other bumper mount points and as such ran diagonally outward triangulating and reinforcing the hitch from racking side to side.
