R35 MAF Adapter for R32

Hi folks, I am looking for a R35 MAF adapter that will bolt onto factory R32 GTR airbox and piping.  As far as I know HPI makes a set:

As I was shopping around for the HPI set, I came across an Apexi adapter that is considerably cheaper:

The listing says this adapter works with Power FC for RB26, but there is no information about physical fitment.  

Would you folks know if this Apexi adapter can fit in R32's factory location?

Thanks in advance!

They're physically the same size as a Z32 AFM.

So follow up question.  How does Z32's compared to R32's?  Will it fit without modification?

[GTSBoy]

Z32 AFMs are physically larger than RB26 AFMs.  There are a zillion mentions of how to fit Z32s to a GTR on the net.

Okay never mind.  R32 MAFs are 65mm and Apexi (and Z32) are 80mm.  I want to use all factory piping so this won't work.  

I will just get the ones from HPI.

Another follow up question.  Are R33 and R34 MAFs also 65mm?  Upon reading HPI's website a little closer, it says their adapter only fits R33 and R34, no mention of R32.

Lost post in this thread was to the effect that all RB26 AFMs are 65mm and all other RB2x AFMs are 80mm, same as Z32.
