Unsolved 3D Models

So I've decided to start my new Monaro mod in a week or two instead of in November - December. Basic bits of info

Have a model from Forza Horizon 3 for the body and interior, but only as a template as I'm going to make my own model with a lower poly count (already done a bit of research).

Have images of a HQ Monaro chassis and will be a making the Chassis model and maybe use an edited Bastow chassis JBeam.

Going to try and find 3d models for a 283, 350 and 454 V8. Old Holden six cylinders (ie legendary "red motor" 186 will come later).

So I've got the basics of it all but just need a suggestion for suspension.

Are there suspension models for a HQ Monaro (have various images of suspension but need 3d model)

Any help or try at helping me will be greatly appreciated. Cheers.
