Analogue-sequencer

I'm hoping someone out there could confirm for me the height of the 
LED spacers for the P3?

The spacers for the 8 3mm LED's are still avialable at rapid by the 
part number on the BOM so unless the part has changed i assume 9.1mm 
is correct.
The spacers for the 5mm leds however is invalid and theres no 
recommendation for a replacement part, i did find an old post of 
colins about someone wanting to change the LED's and he made mention 
of 6.4mm spacers but can someone confirm that is correct?

Thanks
Brett
