I was really hoping you were not intending to make new cuts in the Ibanez body. That is why I used the word 'chew'. It implies a ragged, messy job.

So... to place your new pickups exactly where the Strat pickups are located...

If your guitar has a 25 1/2 inch (~65 cm) scale length like a Strat, you can apply the Strat dimensions directly. But if it is different, you will have to 'stretch' or 'shrink' the dimensions proportionately, in order to keep the pickups at the proper position relative to the string length.

If you don't get a reply from someone who can provide the dimensions, you will have to borrow a Strat, or at least a strat pickguard, to copy.
