These frames are not that hard. Have drilled a couple bolt holes in mine, 3/8" up to 1 1/2". A bit less than $10 should last 8 3/8" holes. That said the upper frame holes can be difficult with the body on. Solutions I have found are a real long drill bit if holes align, can be costly. Even the stubby bits available are to long and have to be cut down to use a 90 degree drill. Mostly I use a 1/4" Milwaukee 90 adapter and short hex bits that I step up twice to do the upper frame holes.
