So basically it looks like there are 3 options here?
1 - use old bracket, modify it to accept new (mechanical) tensioner - use old-style PS pump and lines, but find different (non-OEM Volvo length) timing belt.
2 - use old bracket, use old style hydraulic tensioner and PS pump, bolt up to RN engine.
3 - use new bracket, use new style mechanical tensioner, use new (99+) steering pump and new style PS lines.
Is that right? If switching over to 99+ style PS pump, what else would be needed besides the lines?
