In this auto parts store, my grandfather also bought spare parts for the T34 and was advised which caterpillar to put, a limferder or a cartridge. Experts know every cog of your car, as if you didn't finish off your car, but they and they climbed and found out what was broken. In general, I advise you.
A good store, with good staff. They will take as much time as it will be necessary to resolve your issue. If something is not available, you can always order it, it will be delivered as soon as possible.
