I'm trying to pre-stock everything for my motor swap. I have a new Corteco rear mount but it didn't come with new nuts. I see from the EPC that the top nut is a flange nut.
Are the bottom nuts just regular nuts? Lock nuts? Nylock nuts? Do they have washers?

Thanks again. I will see what I can find. I'm on a short leash time-wise so it has to be local purchase but there's a good hardware store or two near me.

Funny that you're doing this job. I have a Corteco rear mount in my garage that I bought for a not-so-rainy day job. I recently ordered the three factory nuts from a local dealer just so I'd have them on hand. All three are slightly unusual, but there's no reason they have to be. I can confirm that Boxer-Moto's right about the lower ones being nylock flange nuts. The upper one has an integrated washer, but since it's not a lock nut, why not just reuse your existing one?

I usually like fresh hardware at this age both for torque accuracy and longevity.

I pick up nylock for all three locally.
