So took the seats out of the Drover last weekend. The mounting arrangements for the two seats are quite different. The drivers side has a cross-member that the front is attached to and the two bases for the seats are totally different arrangements. Any idea why?
I have a pair of MX5 seats to go in (my originals are stuffed, both upholstery and bases) and it would be a heck of a lot easier if I could just remove that cross bar and mount both seats the same way. Is there a good reason I shouldn't do this?

Noting that this is not going to be a road licensed vehicle and won't have seatbelts fitted nor is it designed for high speed operation.
