Questions regarding Chain Rings size to what Crank Arms size

I don't see how we can justify giving advice that standard five-arm compact-drive cranks are hard to find. And therefore you need to pay such a large amount for RF Turbines. That's nowhere near being true. e.g., all Shimano CD cranks from 94 to 96 were five-arm with BCD 94/58, such as XT M737. The last time I bought some M737 they were £25 if I recall.

You need a nice matching granny ring.
You don't seem to have been given the granny spacers, which should be sold as part of the crank. You'll need to buy these and they are longer, probably 7mm with an Alu granny or 8mm with a small steel ring, give or take a few hundred microns as I cannot remember the exact lengths.
You'll need a full bolt set. CRC for these, 5 triple outer and 5 16mm inner.
A 107mm bottom bracket, and do use grease on the tapers as per Raceface instructions.

Down to the real basics.
I've never bought any spacers, but try searching or put in the wanted (as I'm sure others might be able to point to them) they are not a common length.
See the granny bolt holes (the 5 inside one)
Bolt the granny ring on and it'll flap about, it goes over the bolt between the granny ring and the crank.

If I come across a picture I'll post it up.
