- Power Trim Cylinders For use with all Alpha One Units (1983-1990) Regardless of Engine (2.5L 120hp / 3.0L 140hp / 4.3L V6 / 5.0L 305 V8 / 5.7L 350 V8...etc)
- However, THIS IS NOT XD Trim Cylinders (14035-1 & 14034-1)
- These were used basically in for the 1983-1986 models before they started putting the XD trim arms on everything.
- Please check what numbers are stamped on your cylinders as you will need to swap the lines from yours to these ones, or contact me and I can likely include used lines for an additional cost.
- Stamped part numbers are 98704 & 98703
- These are equivalent to 98704-1 & 98703-1 but are of just slightly earlier design and a bit longer.
- Starboard Cylinder is 98704 (which is equivalent / also referenced as 98719, 98704T, 98704A10)
- Port Cylinder is 98703 (which is equivalent / also referenced as 98718, 98703T, 98703A10)
- Price is for the PAIR exactly as pictured
- You will need to install your existing trim lines on these
- Purchase with confidence!
98704 vs. 98704-1 & 98703 vs. 98703-1
- The 98704/98703 cylinders are slightly older than the redesigned 98704-1/98703-1. These older cylinders were a bit longer overall. It is generally in your best interest to match exactly what you have already stamped on your existing cylinder(s) you are replacing.
- The Trim lines / hoses on these are all interchangable between the 98704 & 98704-1 etc....
