I got the Lee kit today. The tranny cover should fit right on the HL once the HL gear boxes are out. It has nice screw mounting tabs in OEM placement. The kit plastic is very tough, very different from the white urethane we are all used to working with in cottage industry hobbies. The castigs are good quality and fair detail especially for this tank.
There is one spot back right corner where the turret barbet spash ring is slightly straightened causing the turret not to fit, a dremmel and some fine grinding is necessary there.
