New MGF Wiper Motor

Hi, everyone.  I have a 1998 MK1 MGF. I am suffering with dreaded wiper motor fatigue. I know and have read all about the removal and replacement of it on here, also the stripping down of the motor to replace the rusty bearing. All very useful and in my case 85% successful. What I am after is a source from the wide world of a replacement aftermarket wiper motor, not £100 plus job, just a good quality motor. I know people have said get a Freelander MK1 motor it is the same but I still haven't got anywhere because I don't have a part number or a model number for the motor. They just ask for a VIN number and then say its not listed against their motor. Apparently there is also some sort of query about the switching arrangement on the motors offered. I just want to be able to reconnect if possible. Please can anyone help me out?? Thanks in anticipation.

The Freelander motor might look the same in all visible respects but you want a wiper system that functions & not one which blows fuses & makes you, if you are not ordinarily grey, grey.
The problem is in the earthing & that is to do with the switching; our switching is old fashioned mechanical positive pole switching, whereas the Freelander is switched via electronics which is negatively switched.
This crops up every six months or so, I could do with a Freelander motor to see how this problem can be easily circumvented.

Afterthought:
if the motor can be isolated from the car earth? In effect a floating ground, then the motor frame could be either positive or negative ground, depending on which motor is being used.
I’m in my chair in the sitting room with the dog on my knee, the fire roaring up the chimney & thinking it through, if anyone can see holes in my thought process please join in.
M again.
