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 the commercial name of a weed preventive made by the Lebanon Seaboard Corporation and designed to prevent new weeds from sprouting in your vegetable garden. Preen may be applied to the ground just prior to planting your vegetables or vegetable seeds. Preen will not taint any produce that you grow.
