Love that van

My plan is to make it exactly like it was provided by Motion in 1972.. All parts will be put in including the hone o drive and 4:88's. All parts are being restored or replaced with NOS. My biggest issue is the headers and side pipes as they will have to be made unless a reader has a set.

thanks

I sold 427king a NOS set of Kustom sidepipes that would be perfect for this car. Not sure if he still has them or not.

I provided the motor and interior for review. The motor and full drivetrain is now out of the car. All parts and colors to match back in 1972... This will be an expensive project to put all parts back in place as a full rebuild is underway to ensure all is well after 27 years of being dormant.

Enjoy and more to come when in final stages!

Nice! Appears to be a later built 72 with the seat belt warning light in the dash. That had to be in place by January 1972. It started showing up in November 71 built cars. Odd that it has a 70 Air Conditioning vent on the drivers side.

Where was the car built? Baltimore or Leeds

Thanks for posting pics. I would have to say this has to be the "Ultimate" 1972 Chevelle!

I saw a post where a guy built his own set of header side pipes starting with a generic header kit that comes with a bunch of pre bent tubing and header flanges

I think the kit was from Speedway Motors

Here are the headers I sold to Chuck.

let me know if you friend has the headers and/or side pipes made by Kustom that could be used on a chevelle

Joseph,

The car to my knowledge is a Baltimore built car and it was delivered to the owner in December 1971. It is an early 1972 Chevelle. As far as the vents, it is the poor man's air condition system ("astro ventilation system).

thanks,

These are the exact mfg headers that were on the car in the article and were specific to 68-72 Chevelle. I have no idea if 427king still has them; you should ask him. He's a site sponsor and is here regularly.
