I haven't driven my 1987 in a long time but just decided to see if I could cut a track through about a quarter mile of snow up to the plowed road. I got about a hundred yards up and carelessly backed into the deep snow and high-centered the car.

The left front tire and the rear right tire spin. The rear left is on pavement but it won't lock. Last time I checked by jacking up the rear end and spinning a tire it seemed to work. When the rear wheels have locked on mud or snow before it was often with a big clunk.

Does anyone have any tips about what I might do to encourage that wheel to lock, or do I have to wait for the snow to melt? Maybe there's some trick with the clutch or gears? My back doesn't work very well so I can't dig it out.

I searched the site but can't find anything useful.

Thanks.
