I did my shocks and springs last year. It is well worth it. My spring compressors are both slightly bent and ancient. I keepmeaning to replace them, but I never remember when I am not actually using them.
I never thought about a gearbox mount. It makes sense that there is one. I will have to get one and get it fitted.
Not done the subframe bushes yet. Not really been the weather for it over the weekend.
I am looking forward to the result to be honest.
