It's as closest to a direct bolt up for an alternate M/C than any other. You have to make up jumpers to connect the stock lines to the opposite side of the Spitfire M/C. Unlike the S2, the brake lines from the M/C is continuous to the rear of the PDWV so it's more complicated to re-run new lines. Just make sure you get the small cap Spitfire M/C which has the 0.70" bore. All British car parts suppliers should have them in stock.
