Lovely model, but not a Jag IRS. This might be of interest: The first real application of IRS on a street rod came in 1964 on the Don Tognotti “King T” 1914 roadster. It was painted in “chameleon” paint treatment by Gene Winfield, but its hand-made rear end by Walt Reiff was what got most of the attention. “King T” featured a 1955 Chevy center section with the axles cut down to four inches. Half-shafts were added from a GMC truck shortened four feet, and the outer wheel carriers were handcrafted. It was a lot of work, but with all the chrome plating and addition of inboard disc brakes and coilover shocks, the whole assembly was something that raised the bar for rear suspension on a rod, even if it was out of reach for most enthusiasts.
