Suspension Setting for a custom car.

Hi,
I see a lot of really talented people here.
I am building an electric car as a project.
I have built the chassis on 3d, the design is roughly based on a project I saw on Instructables.

I am from India, and I cannot source the suspension components that easily like it's shown in that link.
Is it possible for anyone to help me out with the suspension?

Please send me a pm or reply below.
I would like to get in touch
Thank you for reading.
