...And this question is gonna sound so stupid, but that's why I'm posting it. A stupid question's better than a stupid mistake.

Could I throw a left handed Jazz Bass neck on a right handed Precision's body without any troubles?

I'm mostly worried about exactly length/intonation problems/fit/etc.

What'll I need to do? If it's nothing much (a little shimming, a little shaving, or something) that's no problem but I wanna know WHAT I'm gonna do before I go and buy a LH J-neck.

No, I'm not telling you what I'm doing for pickups, that's my secret
