Hey leone glad to see you are getting close to having it in there, I'm sure you will be very motivated once it is ! When I was reading up on doing the ls1 conversion the auto trans fitted in the tunnel but you need the turbo 400/700 trans crossmember and yours is the 350 one but you may be able to modify in some way ( not 100 percent sure of this ) I hope it just slots straight in there for ya tho
