They should but it will more than likly ratchet on you. 7t is a tight bend for the track. You might want to do some porting on the track to get it to bend easyer.
It shouldn't ratchet a bit. I have my track loose as a goose with 7t drivers and it still doesn't ratchet. You'll clear 2" on the front exchangers and with a minor lift in the rear you'll clear the almost all the exchangers but it'll still rub on the very front.
I have 8 tooth drivers and a 1" track lug with another 1/4" carbide tip on top of that. i have about 3/4" to spare, so you should be ok with the 7 tooth drivers if you don't stud. this is just a guestimate by goign what I have on my exciter.
