I'd like to help, but not sure what you're looking for. I think the C4 had 28 spline, and the driveshaftshop.com should be able to supply a micro-stub for CV use in them.
I was looking at your part Chris but you aren't making them any more. The spindles are from a C4 Corvette. I counted 28 splines which fits the C4 hubs I got to fit the DBR bearing carriers I have. If a different hub would fit for which spindles with CV ends are available I would be happy to get those.
I read here on the forum some time ago that RCR uses a Corvette hub But if they are not C4 the number of splines will be different...Seems things differ from year to year (someone couldn't make up their mind).
I will contact RCR. Perhaps their hub will fit the DBR carriers. I can use what I have for another project so it would not be a total waste of money.

Can you explain what it is your looking for ? I have spare C4 splined axles and CV's that I used on my DRB but not sure if this is what your looking for.
