Jeep TJ Seat Extension by Parts Jockey
If your anything like me (i.e. over 6' tall) then you lack a little leg
room in the front seat of your Jeep. Fortunatly it's an easy fix that
doesn't cost any more than a few bucks at Tractor Supply Company and a
little bit of your time. Here's a quick run down of how I did it in my
'97 TJ
Parts List Cost
Qty 1 3"x 12"x1/4" steel plate $11.99
Qty 4 ½"x 1" Grade 8 Bolts
Qty 8 ½" Grade 8 Flat Washers
Qty 4 ½" Grade 8 Lock Washers
Qty 4 ½" Grade 8 Nuts $3.00
Parts Total $14.99 Told ya It was a Cheap !
Tools Required
Angle Grinder, Cutoff Wheel, Sawzall, Really Sharp Butterknife or whatever
you choose to cut the steel with.
27/64" Drill Bit
½" Tap
Drill
Now, on to the easy stuff!!!
1st, some pictures
Drivers seat all the way back before modification

Step One:
Take your butterknife (or cut off wheel if your lazy) and cut your steel
into 4 4" long pieces
Step Two:
Mark and drill a 27/64" hole ½" in from each end, centered
long ways from front to back.
Step Three:
Take your ½" Tap and tap one of the holes in each plate.
Step Four:
Insert your ½" Grade 8 bolt and flat washer into the hole
you just tapped and tighten down.
Step Five:
Remove your seat. There is one Torx Bolt and three hex head bolts. I don't
remember the sizes off hand.
Step Six:
Take your seat bolts and loosely install the extension plates we've just
made to the floor board. Notice I did say loosely, we'll tighten them
up later. The next pic shows what your floor should look like after this
step

Here's a closeup of an extension plate.

Step seven:
We're almost done here, Drop your seat over the bolts sticking up out
of the extension plates. I used ½" which was a little bigger
than the factory bolt. Because of this I had to open up the back two holes
in the bottom of my seat bracket. After you have everything lined up you
can go ahead and tighten everything down.
Here's the Finished Product Look at all the extra legroom compared to
the passenger seat!
A few last notes:
This mod took me bout 45 minutes from start to finish.
You may want to trim the carpet back around the rear brackets if you're
the type that removes the carpet often.
