I think on old board I asked this and got the answer, but since that was lost...

What's the measurements for spark plug wires to 73 and laters BB ?... earlier engines have wires routed different so measurements are different.

I make the spark plug wires by myself.

I made a kit once with this measurements to fit on my 74

7----------- 145cm ( around 57" ) boot 90º
5----------- 130cm ( around 51" ) boot 90º
3----------- 115cm ( around 45.3" ) boot 90º
1----------- 100cm ( around 39.5" ) boot 45º
8----------- 100cm ( around 39.5" ) boot 45º
6----------- 80cm ( around 31.5 ) boot 45º
4----------- 60cm  ( around 23.5" ) boot 45º
2----------- 40cm  ( around 15.7" ) boot 45º

I know all plugs should it be 90º with number 8 exception on 45º but there weren't enough 90º boots at dealer. Also maybe 2,4 and 6 should it be maybe 5 cm ( 2" ) longer.

I made 8 and 1 wires same lenght... fits really good but if some of them must be longer which one will be... probably 8 ?

I would wish to compare with original measurements... remember 73 and laters route is different than earliers. Also would like to get earliers measurements to compare.
