MGB mechanicals by Year

[DANIEL RAY <danray@bluegrass.net>]

Can someone direct me to a website that lays out the differences by year =
of MGB mechanicals? i.e. emissions equipment, when they went to dual =
brake systems, etc.. Or am I just gonna have to shell out the dough for =
a book? I could swear I've seen this somewhere, I just can't remember =
where!
TIA
