not looking for a rear cap ...just a pre fit fiberglass panel to replace where the 3 rear window go....
TIA guys and gals
Don't know of any such thing, cut to fit metal or sheet plastic is probably your best bet although both will move in the frame when heated by the sun.
Even better is just cover over the openings with sheetmetal.
Personally I like the rear windows but they are hard to find.
You can destroy the 4104 look like I did by installing a R&M fiberglass cap, I have caps front and rear but I miss the old rounded stock look..
My 4104 appears stock on the outside and it is beautiful.
On the other hand my 4107 has caps on both ends and RV windows so it has lost its original beautiful lines, no more Buffalo!!
