hello, I most likely have to repair my saab 902 wd^^ the following must be done: – shock absorber front -cross-over handle -shaft sealing gear – track rods with head – exhaust from kat shock absorber and exhaust I would do alone, how does it look to share with the others? can you change the also relatively easily yourself or do I need special tools? how do you change the shaft sealing ring at all? the gearbox can hopefully stay on top of that?! lg
