I acquired a Saito FA-182T and want to replace all four plugs. The problem is, the front plugs have very little clearance from the fins and valves so I need to purchase a thin walled long reach glow plug driver. Looking at Tower and Horizon, it's hard to tell if any of their drivers are thin walled.

What driver do others use to change the plugs in the FA-182T or do you know what drivers are thin?
