Help fitting McR-19XR and PXR19 heatsink in C maglite

Hi ,
First thank you all for the gret help you are giving in this forum!:grouphug:

I 'd like to fit 4 crees led in my modified C cell maglite but i am wondering if my torch has space enough for accommodate the height of heatsink + reflector.
McR-19XR reflector
PXR19 Heatsink
Form the data sheet the reflector is height 19,89mm I don't now the height of the heatsink , but the space in my maglite head is 20 mm!:thinking:

Is there some mistake in my thoughts?
This is a photo of my modified light head.

The yellow dot is the body of the maglite.
I shortened it and I made a new longer thread , I think I have to cut a little part of it for accommodate the back of the heatsink am I right?

Thank you and sorry for my approximative english,please not laugh too much with my dumb questions:bow:

No dumb question, only dumb answers. Your English is fine.

Try the Modding section.

Is there enough space? I don't know since I have neither the maglite or the hearsink.
