Hi. Looking at some new bar options as my 96 came with some 9" high bars with only about a 3" pullback, sorta like high drag bars. no more stock risers

my three questions:
do we need dimpled, drilled or neither on our bars (my guess is neither)
does anyone have some part numbers for the stock 1" risers and clamps to see if i can get some OEMs
any 1" bar ends and grips should fit yeah?
planning to throw on some 10" apes like this
