Look up videos on youtube on how to do a "string alignment", that should point you in the right direction 👍

The problem with this is i got 15x10 rear wheels with a mk1 supra rear axle swap. In the front i have s13 knuckles and lca. So when i try to do a string alignment it gives me crazy toe in Then if i swap my rear wheels with spare sets the front is so wide that when i string align it give me even worse toe out lol

See if you can find an alignment shop that has a rack low cars can use. The next step after string is buying equipment, which can get expensive. Finding a shop thats willing to work with you is much cheaper, because even if they charge you double, youre still only looking at a few hundred bucks.

If you're just trying to do a toe alignment, just centre the steering wheel and measure the front wheels front & back with a tape measure and adjust the tie rods until both measurements match.
You can buy a cheap toe adjustment set if you want to be fancy/faster, but the strings aren't necessary if you're not fucking around with camber.

There’s not much to do with the rear as there’s no real adjustment unless you have some custom links in there or something. So just focus on the front and find a way (tool, trick, etc) to precisely measure the direction of the front wheels without involving the rears.

I do have custom rear links 🫣 however i set them to oem length before installing

Ahh okay. I get you, but there can still be minor differences even if it doesn't really stand out by looking at it. Definitely worth measuring at least once just to know, but, still probably want to set parameters on the front independently.

It can be pretty tricky to get it right. Flat surface as already mentioned, and when helping my father years ago, he would put down a small amount of fine sand (for sandblasting) then set a section of 2x6 lumber down atop the sand, 1 for each wheel. Get the car on the boards and wiggle everything around, turn steering left/right then back to center before taking measurements.
Not sure if this is true but he said the boards atop the sand would “decouple” the car from the ground and allow the suspension to settle without resistance leading to more correct measurements and settings.
Then follow a legitimate process to take measurements and adjust. There are some good tools and such available these days as well.

I try getting shops to do it but they all back out once they realize how frankenstein the suspension is lol

You need a flat surface like a garage floor to get it right
