Are some 2621 and 2611 parts interchangeable?

Re: My previous post about needing parts for 2621-46X:
Does anyone know if some of the 'case' parts are interchangeable between the 2621 and 2611 series i.e. the casting into which the right hinge inserts and to which its retaining screw is fastened and the little plastic part at the right hinge area?

Thanks,
