Conversion 97er Escort Kombi on rear or all-wheel drive

Who knows a possibility or a kit to convert an escort clipper to rear drive – or possibly to four wheel ?? It is already the second winter in which I lack the rear drive. With the 1st and 2nd Escort model I always got along well – but now – with front drive I have problems.If I find no solution I would have to change the brand to find a Hechtriebler combi.Also for the trailer operation…
