69 camaro mini tubs with 345/30/19 tire

[Twinstang]

Just wondering using stock frame rails obviosly notched and plated on a 69 camaro running a 12".5 wide rim with a 345/30/19 tire can it be done with DSE. tubs or do I need to modify the outer wheelhouse also ?

Also has anybody used the chrisalston chassis works mini tubs they look to be similar to the DSE Mini tubs and what's your experience with them if you have used them.

Thanks,John
