99 Silverado seat track extender

[FS560]

I had hip replacement surgery and would like to have by drivers seat go farther back to create more legroom.

99 X cab (3 door) 40/20/40 manual seats.

Are track extenders made by any source?

Does the power seat go farther back? If so, how much?
If the power seat does have greater range, are the electric circuits under the carpet so that I could simply buy a seat and install it?

No theyre not, plus youd hafta change bcm's only thing I can think of is removing the stop inside the rails or moving it bsck further if even possible or just drill new holes and mount it back more.

Redrill the brackets is your best option.
