I recommend you try the MG Magic route. The Beetle bumpers will have too much of a curve to them and will be too high.
You might want to watch ebay for a while. For example the starting price on this listing
350105505106 is only $69.95 for the blade. There are no bids yet, so it’s hard to predict what the selling price will be.
