Working on the brake(s) ( as in the front )

[Lokin4AReason]

Hello all

I am just wanting to get some insight or feedback on at hownto tackle this . I have drum(s) all around and want to convert my front drum(s) to disc . Well my question would be ;

What year c10 spindle(s) should i consider in keeping my 6lug stock wheel(s) ( dont want drop it ) and the clearing the caliper(s) the stock wheel ?

Or

What aftermarket brand(s) are preferable in sourcing out option(s) on having this done ?

Thanks for the helping and looking . . .
