I have a 1988 YJ. I got a quote of $900.00 for parts and labor ( new pressure plate, clutch disk, slave cylinder, pilot bearing) from one shop. Another shop qouted me a labor only rate of $600.00 if I provided all of the parts.
Preen is a pre-emergent weed prevention product. It prevents weed seeds from germinating instead of killing existing mature weeds. Preen works on a wide variety of annual weeds, but it won't have an effect on perennial weeds because they already have established roots.
Preen is not a weed killer, it is a weed preventer. Let's sprinkle some Preen and show you how it works. When activated by water, Preen bonds with the soil in your garden. Preen then forms an invisible protective shield. It actually prevents weed seeds from forming roots.
