MG TD TF 1500 - Installing TF Seat Rails
|The seat slides are mounted to the floor with a T-nut on the front hinge (I can't tell from my car- that area was rotted out and T-nuts were gone). I did find screw holes at the rear floorboard. Were the slides screwed down there also?|
Should I wait until seats are restored and the slide is screwed to the underside of the seat before marking holes to drill through the floorboard?
|TF seat rails are secured at the front hinge only, so that the seats can be tilted forward. See my response to your question about carpet.|
If you first fit 1/4" x 1" wooden strips to the floor boards, under the rails you can cut slots in the carpet so it can be removed easily. It also stops the rails wearing through the carpet.
|It's amazing that the only thing holding the seat to the car is two T-nuts that are mounted to the floorboard by 3 little tacks. |
I'll take extra precautions when installing the seat belts.
What size T-nuts went into the floorboard?
I believe six 2BA T-nuts were used to hold the seat wood base to the slide.
|oops, I meant it takes 8 T-nuts per seat to connect the wood base to the slide.|
TF seats were originally affixed to the floorboards by set screws(x2)
at the front AND two(2) to four(4) woodscrews at the rear. Look for the holes in the seat slides for these rear positions.
I stand corrected.
I just checked the original floorboards that I removed from my TF. There are two holes at the rear, below the two screw holes in each seat rail. (four under each seat) I can't tell if small wood screws were used or if machine screws + washers + nuts were used. The holes aren't large enough for tee-nuts.
I did a fast check of my TF Operation Manual. There was no reference to tilting the seat forward - which of course couldn't be done if the rails were screwed to the floor.
Personally, I'm glad that the screws are not in my seat rails so that I can tilt the seats.
Thanks. I'm trying to learn something new about my TF every day!
|I wonder why hinges were installed on the rails if they were meant to be "untiltable" if screwed to the floor, but my old floorboard has those 2 screw holes per rail (Wasn't sure if this was factory or PO-installed). The little wood screw don't add much strength to keeping the seat down, but like Lonnie said, I do like the idea of tilting seats forward to access the side curtain box while the hood is up.|
Were the seat rail hinge T-nuts 5/16 BSF, as I have read? I'll have to get these from NTG in England.
Yes, 5/16ths BSF T nuts is correct.
I had a close look at two(2) original sets of TF floorboards again yesterday and it seemed the rear,small holes to pin down the
slide runner frame to floorboards, did not go through the full section
of the plyboard. Therefore,screwing not bolting must have been
