120mm Track hub on 130 mm road bike?
I just bought these, the rear hub is track spacing at 120mm:

for this, the rear spacing is 132.5 mm:

my question is, did I just make a huge mistake or can those wheels be put on this bike with some spacers and an extended axle? please help! thank you!

Mistake maybe in terms of style, but can't tell from a picture what hubs they have, but imagine your solution to keep the pretty white wheels would work if they have that type of axle.

Just put a 5mm spacer under the locknut on each side.

is it a steel bike? If so, don't even worry about it, steel can easily flex that much. 5mm spacers wouldn't hurt, but aren't strictly speaking needed either.

I'm not familiar with the particular hubs, but be aware that most track hub axle lengths are carefully calculated to allow for the thickness of the dropout and the nut so as to come out flush with the nut and not stick out past it. That means there's a good chance that there isn't enough axle for an added 5mm spacer.

Or check out Sheldon's page about rear axle spacing and how to cold set a steel frame. If you know this frame will be dedicated to single speed or fixie riding from now to forever that's how I'd do it. If you want to keep your options open then go for the 5 mm spacers under the inner locknuts. As mentioned you may need a new longer axle. Don't go with the original unless the axle comes out at least flush with the outside of the stock axle nuts. Any less and you're risking stripping the threads over the long term. Mind you if it's about 3/4 of the way into the axle nuts it'll be OK for less strenuous riding for long enough to get to your LBS and get a longer axle. But don't torque it fully and don't do any steep hills or sprints.
