saff front ones are wider and dont lean forward unless you turn the adjuster thing like mad lol, you could try fitting escort runners but i imagine you will have to weld in a plate to make them fit. The rear ones that are in the photo are are saff rears, you would have to cut the 3 inch raised bit off the back of the bench and some how bolt the backs to a frame, as saffs latch bit is int the middle off the two not at the side, i think the guy has used them tho as they dont go to the edge as he has a roll cage bolted to the inner wheel arches so a retrim would be needed unless your goin for a cage and not usin the rear seats.
