TTI tailpipes with factory tips

Has anyone installed factory style (2.5") exhaust tips on TTI tailpipes? If so, how did they fit? Any contact with the gas tank or leaf springs?

Thanks!
I test fit a pair of TTI tailpipes on my '67.
The answer is 'it depends'.
it depends on the how the mufflers and forward are located and hung, and the year.
for '67 with stock located muffler and fuel tank, there will be issues.
