Hi Grace, I'm glad to assist you. They will fit. But if the 11" x 19" is still too big for the pickup, you can check out the other mud flaps we have available for the 1988 Toyota Pickup at this link: https://www.carparts.com/search?q=Mud_Flaps&vehicle[year]=1988&vehicle[make]=Toyota&vehicle[model]=Pickup&vehicle[submodel]=Base&vehicle[cylinders]=6&vehicle[liter]=3%2E0&can=CPAE1047 I hope this helps and happy shopping.

Hi Greg, This is for models without fender flares or fender moldings.

Hi Nick, The price is for a set of two which can be used for the front or rear. If you need all 4 pcs, you should order 2 sets.

Hi, To check the fitment please use our Vehicle Selector — which can be found towards the top of the homepage as well as all categories, search results, and product pages — can help verify if a part will fit your specific application. To enter your application, simply select your vehicle’s year, make, model, sub-model, and engine type and click “Go.” Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.

Hello! You will position them where desired and drill holes through the fender to mount them.
