At least two of the AC C77L plugs in my'28 are shot and not made anymore.

I have a set of AutoLite 3036. They fit, but the reach is about 1/8" shorter.

Is anyone using these plugs?

What plugs are you using?

Thanx

Guys a 28 engines use 7/8 sparkplugs. Unlike the 29 which use 18mm plugs.
Steve i use the autolite 3076 plugs and have had no issue. I also have a set vesters as a back up set under the back seat.

Thank you.

Tried to find the heat ranges of the 3036 and 3076. and only determined the 3076 has 3 A-25 heat range reach of 5/8".

I installed the 3036 plugs and will read them after around 100 miles. then compare their respective performance.

Will let you know the results.
