Roll Cages Requirements for Convertibles?

Hey gang,

So I combed through an electronic version of the 2022 NHRA rule book and I see that convertibles running faster than 13.49 in the 1/4 (8.25 in 1/8) are required to have a roll cage. It then goes to explain that the roll cage must meet Summit Street specs. Does anyone know where I can find the Summit Street spec sheet? I read in an older version that bolt-in roll cages were acceptable in unibody cars. Does anyone if this is still acceptable?
