Morris Minor Owners Club

My minor is nearing the end of a mammoth restoration. Today I fitted the carpets and that went very well. What didn't go so well was trying to bolt the seats back in. On the passenger side (original floor) 3 out of 4 bolts were fine, one wouldn't fit no matter what I tried. On the driver's side (new floor) none of the new bolts fitted into the new captive nuts. Why?! So what to do now?

Replace all 4 captive plates with new ones - not easy as I'd need to weld from underneath and I don't have facilities to roll the car, or drill through the captive nuts and use new nyloc nuts welded in place of old ones. Or is there anothe solution?

Has anyone else had this problem? Grateful for views!

On n/s run a 5/16 bsf tap through the dodgy one. The o/s may be a metric thread, you could possibly run the same tap through those captive nuts but best to use the appropriate bolts.

As above - likely metric nuts or possibly UNF. The originals were indeed BSF.

I love this forum, guys you were absolutely right - different thread on new floor (wonder why it wasn't made to BSF as original). All bolted down and I managed to do the dodgy captive nut on the passenger side too. Seatbelts next

Repro stuff is often, if not always, fitted with metric because it is the easy option, some companies can't get the panels right so the last thing on their minds is the thread type. I've always been puzzled about panel inaccuracy because it just as easy to work to one set of dimensions as to another, so why select the wrong ones. Big mystery!

yep

unfortunately i'm losing one garage accomodation and all my taps are in a pile on the floor - under the boat engine . what fun to sort out !

For Seatbelts, I used the inertia on Securons website, not cheap but seem ok. I have a Traveller so be carefull what you order. I seem to remember the size they recommend is too short (on the rear Trav seats). Its the front stems that cause the problems. Im sure I used London Taxi Stems and I fitted the red belts that are an additional £20 each but nice. They have a useful phone advice. Also, search 'Securon' on this forum and it brings up advice from others.
