hey mate, i know i’m tacking onto a near 4 year old thread but found it a very interesting read.
i always thought that the 200b 5 speeds were conventional pattern and longer than the 1600 4 speed.
i have a FS5W63A dogleg which is same length as the std 4, and assumed it had to be from a SSS stanza, but maybe not??
i have yet to put it in the car but i think it can use the standard crossmember but installed backwards, and also the original bolt holes maybe need to be elongated a further few mm, is that what you found also?
cheers
