The originality of the chassis was incredible with all original suspension components, shocks, exhaust, tags, inspection paint marks, brake shoes and pads, wheel cylinders, etc. Nothing had been replaced on this car and ALL were restored other than brake and fuel lines which were replaced as well as obviously the exhaust system. All the tags and ink stampings were reproduced for the car. Not an easy or cheap job but the over the counter reproduction pieces just don't cut it.

Some interesting things to note here;

orientation of the engine mount bolts in the frame. Baltimore cars are known for mounting the hardware with the nuts and washers on the top side unlike many of the other plants.

Front coil spring decals and placement.

Original dust shields on center link and tie rod ends.

Note lock washers placed behind the stop nuts on the upper control arms which is not how most were done.

The orientation of the rear shock bolts.

The types of brake and fuel line brackets used on both sides. Sometimes you will find an open on one side and a looped bracket on the other.

The original shocks were dated the same in the front as well as the rear. These are presently going thru an extremely expensive restoration and will be brand new when completed.

Looking really good. What kind of Spot Weld machine are you using to replicate those nice welds ???

Awesome work, can't wait to see more, thanks.

Jamie's crew restored the frame to the finest of details. We then picked it up and started the assembly and restoration of the components process.

After straightening, the frame went into epoxy primer and then all the scrapes, minor pitting, gouges, etc were repaired. NO repairs were made to any welds to dress them up or remove wire and was left completely original in that respect. After all bodywork was completed it went into final paint.

While Jamie was doing the frame we worked on other the chassis hardware so as to try and have it ready when the frame came back to us. This was taking place during deer hunting season and a very busy restoration schedule so needless to say I did not get to spend much time in the woods this year.

With regards to inspection marks, we were very careful to preserve everything on the car we found, even the orange paint marks on the rear brake lines that I have been told by some was never done. This is likely the third or forth car I have seen them on so they WILL be going back on.

The spindles were covered in paint marks and were a real mess compared to others I have seen. They were duplicated exactly the same.

All of the original hardware was laid out, documented and photographed. In the rare instance that anything had to be replaced, it was replaced with the exact same piece from GM such as the pinion bumper and some of the chassis bolts.

The steering gear was completely photo documented and restored and rebuilt back to it's original state. The original owner had gotten ahold of a can of black spray paint early on in the cars life and put a flash coat over everything in the engine compartment. Hence the reason for the black paint on the steering box. Note the outline of a decal that was once there. I have no idea what it was and nothing I have researched has come up with anything. I almost see a yellow stamped "DL" on 1970 boxes but found no signs of any stampings on this box. The box was bead blasted to bare cast iron, treated and sealed and all machined surfaces were remachined.

As said earlier, all of the suspension was original to the car so rebuilding and restoring them was paramount rather than to just replacing them. Great care was taken to preserve and document everything. Note the orange markings on the calipers.

The rotors were original and were within tolerances so we brought them in and turned them ourselves. This was we were able to put the correct cut on them as well as turn the outer edges. We also blasted and then dressed up and/or remachined all the machined surfaces on the rotor hubs.


The backing plates were original and in remarkable condition. Unlike what most people think, they are not zinc plated but rather are stamped from a sheet of galvanized steel. Normally we have to replicate this using several different paint methods which is very labor intensive but were able to save these. The backing plate decals were custom made and not store bought.
