Auto Year/Make/Model script FETCH from external site

I have a website where I sell auto headlamp bulbs but not all customers know there size so I want to make a script that fetches information from another 3rd party site.

How it would work:

Step 1:

Choose Make and Year (PAGE 1)

Step 2:

Choose A Model (PAGE 2)

Step 3:

Some cars have a option:

"With halogen capsule headlamps"

or

"With HID (high intensity discharge) headlamps"

***Not all models will have this option*****

Step 4: (link: [url removed, login to view])

High beam headlamp

H7 (Add to cart link here)

Parking light

W5WB (Add to cart link here)

Front turn signal

3457A (Add to cart link here)

[....................]
