I have a 91flhtc and a 07 apc with a 117 s&s 6speed
will the engine and trans fit the flhtc engine and trans look farther apart on chooper

 

The engine very possibly would fit.. Need to check Height clearances.. I know some have installed S&S 124"s. As for the trans, Isn't that a right hand drive 6 Speed. If so it would be a lot of work to convert your bike. It can be down but not sure it's worth the investment...
