There is a door handle on the inside and the outside. Neither uses a tennis ball.
The 4 door is 188.5 inches long and the 2 door is 178.6 inches long according to my 1995 Ford Explorer brochure
Starting with the 2002 Ford Explorer ( 4 door ) the automatic transmission does not have a dipstick
Look on the driver door for a label near the latch with the door open.
I believe the 1992 Ford Explorer four door holds ( 19.3 U.S. gallons )
Look for a sticker on the inside of the rear door frame.
Starting with the 2002 model year , the Ford Explorer four door does not have an automatic transmission fluid dipstick
The 2002 Ford Explorer ( 4 door ) holds ( 22.5 U.S. gallons / 85 liters )
underneath the Explorer , below the drivers door , mounted in the frame rail
I believe the 4 door holds 19.3 gallons
4 door - 21 gallons ( 79.5 liters ) 2 door - 17.5 gallons ( 66.2 liters )
Starting in 2002 the Ford Explorer 4 door does not have an automatic transmission dipstick
underneath the Explorer , below the drivers door , mounted in the frame rail
