Lanc's because you're obviously an Alfa fan I can't tell you what admiration I had about the 33 TT 12. My former boss use to have one - probably a GELO but not sure - but I was impossible to fix it properly and bring her back on the track. As to the tubular frame, Alfa boys had an effective technique to spot any failure in the chassis. Warm oil leak meant a crack on the right side, warm water leak meant a crack on the left side. Easy inspection was made on the driver's legs!! Wattacar specially when Arturo was the ban leader!
