All the C3 stuff is super easy to find Randy, it's that 2 year only 69-70 Single piston caliper stuff that is getting difficult.

And understand that at a minimum, the stock 14" wheel is no more if you do disc of either type. C3 goes one step further, you'll need GM Rally's to clear that big caliper. 15" Wheel Vintiques 62's of any width will not work.

I pmd Randy as I have most of the parts from a 70 2+2 I parted for the the 69 396 2+2. Unfortunately the shed is currently buried behind a snow drift. Itll be a bit before it melts away.

This is very exciting Eric !

Mark is offering to rebuild everything once the snowbank is gone.

To have you guys in this group is amazing.

Larry is heading west in the late spring but we may look at other shipping ideas.

Hey Mark,

You know me well biggrin

Would " 15" Wheel Vintiques 62's" work with this set up ?

Down to the last bolts !

As Clint mentioned, these trailing arm bolts, are the toughest to get at.

So, back to my dad's tool box to see if I had a 15/16 to get in the small hole.

Yep !

Of course, I had a little help from an old friend of mine.

Corded "Nut Buster"

Frame will be off for blasting at the end of the month.

Every last nut, bolt and self tapping screw out !

Now to clean up the mess biggrin

These look like the original F-40 springs.

A lot more beef than the convertible springs

This car should have had a rear sway bar but no holes in the trailing arms.

They could have been swapped out at one point.

Did you get the rubber pads off the top of the rear springs? Sometimes they're stuck up in the spring pockets.

The 15" 62's work with the single piston caliper Randy. I used them on my 65 with the brakes you are pursuing.

It's the big C3 caliper that needs a concave back mag spoke or a rally wheel.

Nice job on the frame, and nothing needed cutting?

The springs on the right are progressive rate. So aftermarket.

The isolators were not there confuse

At one point the springs must have been out and they either forgot to put them back or did not think it was necessary.

Are you going to do a 8" all round, or 8 and 10?

Do you mean F41? Was the car built with F41? An F40 car wouldn't have a rear bar.

ABC123 · Uber Guru

Thank's Carl !

That solves a mystery.

This is a F-40 Car.

Would you still add a bar Randy? I know you are going for authentic, but as you well know, it really is one of the best bang for the buck things you can do to make it a better driver.

Would it detract from the car?

I am adding power brakes, possibly disc to help the drive.

I probably will be adding a rear sway bar but I won't be stressed at finding an original one.

How about 10 all around biggrin

I'm surprised in the documentation that they go as far to specify for power steering, N40 non-variable. I thought that in '69 variable-ratio N41 was used on Parisienne, 2+2 & Grande Parisienne & their cousins Impala, SS427 & Caprice, while constant-ratio was used in Strato Chief & Laurentian (Biscayne & Bel Air) plus wagons.
Check the '69 brochure if you don't believe me.

For '70 all B-bodies but wagons used variable-ratio.

Semantics can get in the way, N40 vs. N41, the general usage of M40 when sometimes it means M38, the many faces of M20... Therein lies the rub.

I might have a pair of decent isolators, I'll poke around the garage.

Brought home the 1970 1/4 the body used as a template to rebuild the 2+2 1/4s

A bit too well seasoned to use but all the measurements, curves and angles are there.

Especially the double lip on the wheel opening, that my body man keeps teasing me about.

In the end, he produced an exact copy.

I'll post the 1/4s on the car once they are done.

Then off to see Bill, (I'm too busy to tell people about).

Bill, a former drag racer and a big block, M-20 guru will be rebuilding the Rochester that Howmac provided.

As he pointed to 3 bins of Rochester carbs, he said that he has a few tricks up his sleeve to add some performance to a GM stock carb.

He will also go through the M-20 for me.

They say that M-20s are simple but I think it's worth it for an expert to look it.

I'll take a look for those rear spring insulators tomorrow.

Thanks

No rush !

Better late than never, they're hard to find in good shape.

They look beautiful biggrin

I may have a local set but I won't know until the that person's vacation is over, at the end of next week.

cdnpont · Canadian Poncho Superstar!

What exactly do they do being so thin? Stop the spring from making a grating sound?

The ones on my 67 were worn through, so I just ran a section of hose onto the top loop.
