After a bit, my grey matter clicked and clunked and spat out a decent idea. Quick bit of cutting and welding and now I have a slip on gantry for my trailer. I'll let the pictures tell the rest of the story.

I worked out the design so that I could pick up a motor (or anything heavy) with the block and tackle, then wind the winch to bring it forward over the trailer bed, so I can lower it and transport it. Then it just slips off when I don't need it.
Oh yeah, and the radiator support panel is only remeved because I'd already done that to get everything else out easier. Would still work easily enough with a complete car...
