Only thing I've managed to find is this listing from the Magnecor plug leads catalog:
VAUXHALL and ENVOY
1979-1970 Cavalier,Firenza,Victor (4 cylinder OHC engine) 4092 4792 4592
1969-1963 Vauxhall Viva, Envoy Epic (4 cylinder) 4084 4784 4584
1969-1968 All (except Epic & Viva) with 4 cyl. OHC engine 4092 4792 4592
1967-1957 All (except Epic & Viva) with 4 cyl. OHV engine 4011 4711 4511
The three numbers seem to be Magnecor part numbers for 8mm, 7mm and 8.5mm plug lead sets in order.
If I remember at the weekend (and if they're still readable) I'll try to get the numbers off the NGK plug leads I have on the Sportshatch. I don't know if you can still buy NGK leads but the numbers might give enough information to match them to something else, or get the specifications.
