C-beam lengths
#2
Fix for what?
There are 2 lengths depending upon whether the beam is off a car with a D36 or D44 diff
The D44 is longer so it's corresponding C-Beam is shorter
Difference in length when a D36 beam used on a D44.
Some redrill the holes instead of getting a D44 beam when doing a diff swap

Thanks mine had engine and trans swap the th350 has a short housing, leaving it bolted to last hole on trans i was thinking of bolting piece off steel in c -beam holes and extended to front hole with spacer to make up diff with c-beam think it will work?

It could be done like this I guess using a fabricated adapter to use the C-beam:
OR if you've already got the C4 extension mounted machine the height of the C-beam mount to use a beam that could be bolted to the c-beam mounts and adapted to what you have. Similar to the snapshot above but to the C4 extension.
Do you have a functional speedo or you don't care?
If you had already the correct output shaft you could likely buy just the spacer from Fitzall. I believe the TH350 needed is the 9" tail-shaft version.

needs to be the 9" tail shaft with spacer...

"ProjectC4" shows a TH350 that if in a build with a D36 would use a D36 C-beam with no modifications OR it could be used with a D44 C-beam in a build with a D44 C-beam.
What exactly do you have for a build?

FYI - I use a 9" output TH350 in my 84 Corvette Drag car. I have the cast alum spacer kit shown above and re-used the tail shaft housing from the 84's orginal 700R4.....
A 9" output shaft TH350 is within 1/2" OAL of a 700R4/4L60. It will bolt right up as long as you have the correct length C-Beam for whatever rear end you have under the car. It will bolt right up.
As said twice above, there are 2 different length C-Beams. One for the D36 and one for the D44.... The D44 C-Beam is about 2" shorter but you can cut off and re-drill the longer D36 C-Beams to work with a D44 (also shown in the pics above).

Yes - there are 2 C-beams. One for a D36 rear application regardless of transmission and another for a D44 regardless of transmission application. The transmission application of course does need to be "dimensionally correct" for a C4 application and your TH350 is NOT.
"ProjectC4" shows a TH350 that if in a build with a D36 would use a D36 C-beam with no modifications OR it could be used with a D44 C-beam in a build with a D44 C-beam.
