St. Therese was the Quebec plant...it's gone now but only in recent years. .
The 3T3 Suffix...there was a post here a few months back with a Canadian '68 big car w/ a similar suffix...of course I can never find anything with the search thing? .
Canadian suffixes were sometimes numbers not letters, yes even Mk1V Tonawanda built stuff...there's a few 4 series suffixes from BB Chevelles known also a bunch of SB ones too...I have a few old listings but think there was no 3 series BB ones when I looked last time...I'll look again anyway. .
The car sounds very cool...the M22 dealer install part too...how's the hood survived? .
