This document is a homemade blueprint titled "90Beater Rock Sliders" showing how to fabricate a set of rock sliders (side frame protection bars), hosted/credited to Topher's World (www.tophersworld.com). The drawing labels each fabricated part with letters A through H: A is the main 67" tube cut with 45-degree ends, B are 3" angled supports (eight needed), C is a bottom tube measured after fitting A and B, D are end caps/tips welded on after assembly, E are 3" x 3" mounting plates (the rear driver's side plate is 3" x 2.5" to clear E-brake cables/brackets), F and G are vertical legs measured in place (builder used 16" rear and 16.5" front), and H is a cross piece measured and cut after G. Key dimensions include the 67" overall length with points, 21" spacing between supports, and the 3" x 3" plate detail. A materials list specifies 40 feet of 1.5" square .120-wall tubing, two pieces of 1.5" x 8" x .25" flat stock, three pieces of 3" x 3" x .25" flat stock, plus sixteen each of 3/8" x 1.25" bolts, 3/8" nuts, washers, and lock washers. A "Front" arrow indicates orientation. A reader can use this as a complete cut list and assembly sequence for building bolt-on rock sliders.

- What materials are needed to build these rock sliders?
- 40 feet of 1.5" square .120 wall tubing, two pieces of 1.5" x 8" x .25" flat stock, three pieces of 3" x 3" x .25" flat stock, plus sixteen each of 3/8" x 1.25" bolts, 3/8" nuts, 3/8" washers, and 3/8" lock washers.
- How long is the main slider tube?
- The main tube (part A) is cut to 67" with points, using 45 degree cuts before cutting off the tips.
- What size are the mounting plates?
- The E mounting plates are 3" x 3", except the rear driver's side plate is 3" x 2.5" to clear the E-brake cables/brackets.
- How long are the vertical legs (F and G)?
- The builder set the sliders in place and measured: 16" in the rear and 16.5" in the front. The drawing shows F at 16" and G at 16.5".
- When should the mounting holes be marked and drilled?
- Mark the holes after all welds and grinding are done, and make sure to move anything away from the frame before drilling.
