Is there a company out there who makes spline adapters that are
weldable? Any other source?
I am trying to get my large hydraulic piston pump hooked up to my 283
Chevy V-8 engine's clutch disc. The pump is male splined, the clutch
is female splined, both have very different diameters. Any suggestions
on how to approach this adaptation? Am I missing anything in how I
plan on marrying these two together? Thanks in advance.

BSF is another possible source. They make complete adapters including a
custom housing and coupling if you specify the pump and engine, but I
think they'll supply just the coupling...
