There is a member on DTW named Ryan that did my first tq converter install and he also does gear swaps. Sam should have his number because he is the one who installed his 4.56's. You might see if he will do both for you at the same time.
Yeah his # is (817)714-5286. He does excellent work, and FAST. He just installed a TC for Randtx and he was real pleased with him. But I would check prices between him and Jason, because Jason does good work too.
