Re:
I'm pretty sure I can help out as I have options. I have a set of arms with the usual heel rub and can offer a few spider options. Standard rings, 104 4 arm bcd spider (new in black), 94 bcd 5 arm spider in silver or original integrated rings. I've got a bottom bracket as well.
I have various rings for each spider would need to check exactly what I have.
I might also have a very tidy complete chainset and bottom bracket.
If anything is of interest, let me know and I'll dig it out and grab some pics over the weekend.
