I have never done this job, one of tech tips is to put a t5 in and mount to bellhousing and being able to retain stock clutch and starter button with no other mods. is there any way those bottom bolts can be accessed except by bellhousing removal? If I read the other posts the engine would have to come out to be able to remove the bellhousing? This my son, who is 21, and would like to be able to stay at highway speeds. Any other suggestions?
