I have a WC t5 in my 34 Ford. 383, 3.42 gears. I modified the countershaft with a stronger bearing with a preload. I don't do drag race starts or powershift, but I lean on it every time I take the car out. No problems since 2003. I know they are not the strongest, but for my uses, it has been great. The quiet, smooth shifting make it a good choice for me.
