no offence but only buy FADAL parts for this, you can end up damaging a spindle if one of the parts are wrong.
Personally I wouldnt add through spindle do to the leaks that have been popping up from time to time and I myself couldnt risk the downtime or expense.
I had it before never had a leak, had friends who have had tons of leaks and had to replace spindles.
When I had it I only used it for deep drilling it didnt work for small endmills very well at 8-10k rpms
just my opinion.
