You could put the foam and batting on then pin on an old sheet, mark off where you want the seams cut it out add an inch at the seam and allow for enough to attach the bottom and back. draw it off on cardboard and use that to cut the vinyl. I would do the front first cut out the sheet pin it back on do the sides pin them on then do the top using the other sheet as a guide. It helps if the sheet is white and you mark the edge with a black marker. If you can find one in the junk yard you might be able to trace a pattern on some butchers paper you will just have to allow for enough at the seams and bottom or back. If the seat cover you have fits well you can put the foam etc. on put the cover on and use the cover by marking the seams cutting it apart and tracing it off. Make sure the inch you add to the seam is accurate so you will know where to sew. The link has some good info in general. http://www.upholster.com/auto/truck.html
