wdp said:The T-9 is good for 200+ horsepower so breakage shouldn't be a problem. Taylor Race Engineering has parts listed in their catalog for the T-9.
pwlester said:I installed one of these transmissions in my TD and Moss has made a commitment to stock parts for it for the foreseeable future. I can't imagine that you will ever actually need any parts running it in an MGA. The Merkur had a far more powerful engine and this is a really nice piece of equipment. The Moss item is a bit pricey but it went in without a hitch and works great.
