K-Factory one-way outdrives, fit AE HD one-way?

[colmo]

Do the K-Factory one-way outdrives, sku K1244-1, for their NTC3 one-way unit, fit the Associated Heavy Duty one-way unit?

The reason I ask is I have the HD one-way but need the HD outdrives (for BJ4 non-WE), and have noticed CML's End of Line RC shop is flogging the K-Factory equivalents cheaply.

By the looks of it, the outdrives I'm looking at are quite a bit longer than the AE HD ones.

Looking at the newer K-Factory one-way (http://www.kfactoryracing.com/production.jsp?id=K1252), it looks much more like the AE Heavy Duty equivalent.

I might get the complete K-Factory unit instead, as it is also on sale, for about the price of the HD outdrives...
