american muscle is great for tech support on which antenna is the shortest. other than that, i suggest getting tech support info from a company not in the resale side of things.
you're basically asking a check-out clerk at Sears for tech support on properly refurbishing your torque wrench... they arent gunna have any idea what you're talkinga bout. lol.
the T45 is a strong-ish transmission. theres a guy on this forum named Matt and his T45 ran until he put slicks behind it. I put my T45 back on my car with 500 horsepower.... the T45 was also used in the 1996-1998 cobras which make 305HP from the factory. what you are doing wont be much further than 305HP.
as for the computer, when i did my swap, my tuner said "we can tune it with the 1996GT computer. But it would be much easier to do it with the cobra system." so i swapped computers. for your swap, it would be rather difficult and cost prohibitive to swap the computer system as well.
as for your steering wheel, chances are, after 15 years your steering rack has gotten old. If you have an alignment place nearby that wont rape you, go get your camber adjusted to simply rule that out. You can also ask them about the problem and they could probably give you better advice, seeing as they can actually see the car. lol.
as it was said in this thread before, call a different company for tech support on your suspension.
