Yes, It can be done, but there are MANY differences between the Silvertop and the VCT. I'd stick with either the old Silvertop or get a newer, non-VCT Zetec from a Focus. I prefer my old Zetec to one of the newer ones, simply because it has less to go wrong on it, and sounds a bit different. Aftermarket on the later Zetecs is much larger tho...
