Don’t be fooled by other tops using boat topping. Boat toppings are not designed for speed and is susceptible to stretching and staging. 

Up for auction is The Sombrero (TM) dune buggy bikini style top. It is made with Cabrio convertible top material. It is offered in 6 colors, Black, White, Dk. Blue, Tan.

The tops are designed to be used with the standard Manx type windshield with the groove facing to the front of the buggy as well as the Manx type roll bar. This roll bar will have 4 bends and will be a single hoop. The two lower bends are about 5 degrees at the belt line of the buggy and 85 degrees at the top. This top will work on a two bend roll bar but you will have a slight wave. Some have used the top on buggies with cages as long as the measurements work and the cage does not interfere with the flow of the top.

 We have two sizes available; 39” and 41”. You will need to specify size.

To do this you will need to hook a tape measure to the windshield frame at the center of the buggy and draw it back over the roll bar. Look at the center of the tube and that’s your measurement. Some may need to adjust their roll bar for the top to work.

The top will come with snaps and D-rings. You will have to provide the 10-24 nuts and bolts for the D-rings as there are too many variables from buggy to buggy.

Please note: These tops are made to order. Please make sure your buggy meats specifications as we do not take returns. Measurements are the soul responsibility of the customer.

These tops have a 5 year prorated warranty on manufactures defects.

The “Sombrero” dune buggy bikini top is Designed, copywrited and trademarked by Tj Kustoms..It is manufactured exclusively for Tj Kustoms. Each top is computer cut to insure quality and fit.

Installation instructions:

The windshield has a groove that should be facing the front of the buggy. There is an extrusion on the front of the top. It fits in to the groove. You will need two 10.24 screws,nuts and washers from any hardware store that matches the thickness of the fiberglass at the upper corners of the rear seat. (There are too many variables to supply that particular part.) these screws hold the D-rings provided. Drill and install D-rings first then fit the top to windshield. Attach rear straps to D-rings then snug up. Make sure top shifts in to place to smothe out the top. (This is best done in the sun on a warm day or a heated garage.) mark location of snaps on windshield. Drill and tap using an 1/8” drill bit and tap slowly going back and forth using a fresh #8 sheet metal screw for each side being held with vice grips. DO NOT USE SNAP STUDS TO TAP HOLES! After taping install studs.

Trim straps leaving enough to maintain a little extra and melt the ends with a lighter to prevent fraying.
