Long Water Pump Bracket Help

[67C10Step]

At the risk of sounding dense, I need some advice. Pulling the original 283 from my 67 and installing a crate engine. The new engine has a long water pump that is going to pose some pulley and bracket challenges. The truck has been converted to power steering and I have that worked out for the long water pump but I really want to keep the alternator on the driver's side.

What are my options for brackets to keep the alternator on the driver's side. Obviously, I am going from heads with no mounting holes to now having that availability but will have headers so no exhaust mountings.

I've read online and even searched this site and my slow uptake hasn't come up with a resolution yet. If it were a simple rebuild, I'd just throw a short water pump on the engine but to maintain any warranty I do not want to do that.

Thanks in advance.
