Fuse box conversion

I am needing (and wanting) to replace the fuse box  / fuse block on my TE 21.  The current original item is a Lucas 4FJ.  I'd like to get away from the glass tube fuses, since they are becoming scarce, and move to a modern blade type fuse.  Have any of you converted to a modern fuse block and, if so, what do you recommend?

Not to criticise your intention to upgrade, but just to note, that the old glasss fuses last decades and are still readily available vis simple internet search, because they are still in use in many cars. They are still very cheap also. Recently bought a couple at £1 each (first time in 23 years), Always wondered  how the modern plastic body fuses will fare in the hot under bonnet temperatures of the TE21. The fuses in all my modern cars are located in the cabin outside the engine bay.
