8mm plug wires in factory holders / retainers ???

[Kimodc]

After ordering Denso 7mm "direct fit" plug wires and seeing how poorly they fit, I returned them and got a set of MSD wires that will allow me to make them the lengths I want, but they are 8mm. Is it just a matter of trimming the plastic retainers on the factory wire holders to allow the 8mm to fit or am I better off going with different retainers all together. I do not yet have factory retainers, but was just about to order a set with all the Memorial day sales going on. The car is a 1969 Sport Satellite with a 440 and AC.

I use those wires with the factory retainers. The wires are tight so I put a dab of grease on the retainer and slide wire into retainer.

I've used aftermarket and factory type "wire looms" and I just grind away a little here and a little there so the wires fit. Obviously.....grind away very, very slowly

Ain't no hill for a stepper!
If you feel the need, fetch some extra from MSD from Summit or some such...

Or use the RoadKill zip tie method

These are 8's. I just kinda' rolled them into the slots. Tight, but they went. No grinding here but more likely the better way to go...........

Same here with firecore250 wires the days they were 8 mm.
