What model combine is itIJ I put one in an R50 last year (not fun) and removed it this year when I installed the Ag leader system. Quess what I an saying I have a new one on the shelf in the shop. Only used very short time. It can be replaced, I used a flat bar with electrical tape run on it with the sticky side out to hold tops of bolts to get them in the hole and the make a set of wrenches that are extra long and extra thin (must be made for this job only) and they will go in the bottom to hold bolt, take a small bend to get flat.
