Location: Parts Unknown | I don't have a truck manual, and a lot of things ARE different for trucks,
but it seems to me that if the crank isn't different for some reason, then
any B-block flywheel ought to be interchangeable. But I can tell you from
my 60 DeSoto experience, my flywheel had surface cracking, but I decided
to use it anyway. I broke three clutch plates in as many days during my
break in of the rebuilt 383 x-ram engine. The stock 10" clutch broke twice
separating the center from the disc. The other time, the discs all separated
from each other.
So, I looked around at muscle car era HP parts to install. One of my motor-
-head engine builder friends suggested I take my broken parts down to Seattle
Brake and Clutch and let them direct me to the parts I needed.
The old man glanced over at the pile of junk I was baffling the young turk
at the counter with and said "DeSoto, eh ? .... haven't seen one of those in
here in a long time !" I am still baffled at how he arrived at "DeSoto" and
not Plymouth or Dodge, as they were much more common with HP stuff like
that in the day. But he did, and then began barking orders to the young turk
about what to get off the shelves for me.
One thing he said to get was a 12" clutch. I spoke up about not having
enough clearance with the pressure plate, and the old guy got up in my face
and made some comment about Baghdad and Dad's bags, so I backed off
and let them be the professionals. I walked out of there for $135 with a new
flywheel, pressure plate, and clutch that the HP guys wanted $800 for at the
time. I put it all together and never had another problem. 1st gear was kind
of sluggish for racing, but 2nd, if hit right, could darn near pull the front wheels
off the ground. It was beefy.
My point ? A dead-stock original clutch set up might not be necessary or
your best choice. Have a look around at other options. As a cautionary note,
my motorhead friends warned that the regular HP clutch set ups were stiff and
not much fun for regular driving. Whatever the old man sold me at SB&C was
not at all hard to drive, so there is something there to also ask around about.
You probably want to drive this car more than race it, I presume.

Location: Alaska | The truck flywheel will bolt up to your engine but depending on how heavy a truck it came out of, it might be overly heavy for your engine. It might also be too large of a diameter for your bell housing.

The Hollander Interchange shows the '57-'58 315 truck flywheel (#210) as an interchange to most '57-'61 V8's including the '58 Plymouth. |

Location: STL, MO | The truck fw may fit the crank but not the bellhousing as some trucks had a hydraulic clutch and the setback/offset on the fw is different. |

Location: Parts Unknown | FWIW ~ The aforementioned setup used in my DeSoto involved a 383 and stock bell
housing. The flywheel was nothing special or that different from stock. But the parts
book called for a 10" clutch and what was sold to me was 12" with a very special pressure
plate to fit the two. That added 2" made all the difference for hanging on to that flywheel
and it never broke again in the next 5 years that I drove the car. I'm not into racing and
rarely hammered it hard. It was perfectly pleasant to drive, but when I did lean into it,
it held up well. No chatter, no slip, no anything weird. Just smooth, easy performance
like anyone would hope for. Wish I could tell you exactly what I had there, but too many
years have passed to remember.
