A guy im my Town had a 63 impala with N50s maby 4 inch
hanging out. And he had  cut front springs  riding shotgun
you had to hold on to the dashbord. The rear bumper was
so high you could drive under it with Another car
I still remember the first time i saw it i was maby 13-14
years old and thought it was the most awsome car ever .
And ofcause he had a superior steering Wheel. 8 inch dia
Cadillac 59 tail lights glued to the stock ones
he tried to pass inspection with it and got 22 remarks
a record that was for many years

I still have some N50 15s Formula 1 Super Stock
any one remember those?   on some 12 in wide slotmags
the widest tire you could buy in Sweden in the 70s
maby some longer shackles and air shocks and i can fit
them on my 64 Galaxie

I actually kind of like the steering wheel.  Back in the 1970s when you bought a car like that, adding a custom steering wheel was one of the first modifications people would make.  I can understand the desire to keep the car stock, but that steering wheel looks good in there

Yes a good old Superior 500 first thing you  bought and mounted
then some Slotmags or Cragar SS
If you had lived closer we could have swaped steering Wheels
beacuse i Think i have a stock one from a 65 i had
You can fix the cracks.
If you have Another old Wheel grind of some of it and
mix it with epoxi glue and fill in the cracks and after it dried
you can sand it smooth and paint the Wheel in the desired
colour

If there is a DIF cast on them they are cast at
 Detroit Industrial Foundry and if you have a
C encircling an F(if my memory is right)
 they are cast in cleveland

I know i have seen some old Engine (probably 1920s) with 4 valves
and "fork" rockers. I dont remember if it was car or
motorcycle engine

The thing with fiberglass...If you take a steel
body panel from another car it almost never
fits 100 %. Not even new oem parts fits
  But with steel you can bend, it stretch it,
hammer it in shape and it stays there.
But fiberglass springs back .And if the fiberglass
parts have been sitting on a shelf it change shape
after a while. Dont buy it Before you are ready to
mount it and buy it fresh from the mold.
So dont kick your self for not getting the ebay fenders
probably been on a shelf for years.
Fiberglass parts have a bad rumor beacuse of this
Yes there is realy bad fiberglass parts out there
but some are better but not perfect
But almost no steel parts is 100%perfect
take a look at the amount of shims on some fenders
And with a frame built car things can realy missmatch
depending on how the frame/body is shimed
a perfect fitting door from one car can take a lot of
persuading with 2by 4,and portopower and shimming
to fit Another car.
If you try that with fiberglass you end up with  broken parts
