Propshaft too short?

I've been getting noise from the drivetrain on my Roadsport SV and took it in to have the gear box overhauled

The garage has pointed out that the propshaft looks too short as there should not be so much of the section that slides into the back of the gearbox exposed - see photo 

I've been advised that the propshaft can be lengthened to address this.

Any advice you can give me in this would be welcome!

Have you still got the Caterham part label on the propshaft?  Its worth a look, even if faded over time.

Too short IMO, I had the same problem when I bought my car sent it to https://www.dandfltd.co.uk/. Great service, they put a complete new tube on, balanced and checked over U/J's, came back within 2 days and the price was very reasonable Thumb Up

Bailey Morris are the OEM supplier based in St Neots.

That does indeed look short - I wonder if its an S3 prop. IIRC mine has 1/2"-3/4" gap.

How do you measure prop shafts: between centres of the UJs?

Too short IMO, I had the same problem when I bought my car...

Anything special about the history of either of the cars?

I wonder if its an S3 prop.

Nice explanation.

Mine is a 1990 kit and originally an X Flow. When I spoke to John and Mick at Redline about the problem a few years back, they told me that when CC ran out of stock of the correct shafts it was common practice to send out the slightly shorter Vauxhall units  Whistle

Going back to as far as 1994 there have been circumstances where the prop shaft supplied by CC have been of the incorrect length.

The prop shaft on my second Seven a 1.6K (2000 model home built) was too long as when I drove it for the first time it barely got around the block before 'stiffening up'. This also did not do the gearbox any good.

CC were aware of this problem but did not share it so they paid the price for rectification even before the car went for IVA.

That is about the play what you need for a Live axle so i can't see why it shouldn't work.

Play? Live axle? Why it shouldn't work? I disconnected one drive wheel drive shaft to get it on the CC trailer. That is how stiffened up it was.
