I am starting planning for this project

[url

I have been doing lots of internet searches but little is available.
Any knowledge you can share about this car would be greatly appreciated.
I am intrigued by what type of chassis Ray Nichels would have built
Did he retain the GM short arm/coils rear or something else?
Again same questioning about the front, standard GM or something else?
I believe this was the period where Nascar was migrating towards the long arm rear and Galaxie front clip setup but I have no idea if this car had integrated any of these ideas.
A call to the experts and historians for your insight, and any pictures you may have in your files for chassis, engine comps or interior.
Thanks![/url]

Check this out, may provide some useful information.

MPC made a model of this car. But don’t know how accurate it was.
Never liked this car, especially the color & the owner.

There are a couple of interesting build images of the original Nichels car on another car modeling forum showing the fabbed front clip and side cage bars that protrude into the door cavity.

Keep in mind GM intermediates had a factory wheelbase of 112" - which needed to be stretched to 115" for Cup competition. You may notice on some images how the rear wheels are pushed back a bit.

The original MPC issue has a chassis/cage that is all wrong for this car, except for maybe the front clip and acceptable GM-style head/valve covers. I'd use a '90s AMT Tbird chassis/cage as a basis.

Thanks Bill. I remember seing that picture but I can't find it on the web.
Good advice on how to set the front, roll cage and pushing the rears a bit. I will plan for that.
I still need to figure out if I should go with a short arm rear ou truck long arms.
Thanks for the help!

What are you planning on using for an engine?

Good question, I don't know.
I'm building off a production spec GTO kit which supposedly has a 400cid small block so we'll see if this could be useable

Below, comparing a production GTO and the Nichels race car. The guidelines are set at key areas of the production car. Note where they go out of sync on the race car.
( these shots were taken through different lenses - a telephoto on the blue production car, and a wider angle lens on the Pearson car, which makes that one distort a bit especially at the ends. However the guidelines show the modification at the rear wheel pretty well.)

Wow, thank you so much!
By looking at these picture, looks like there wasn't much stock left in this stock car.
