Mk 1.5

[badhuis]

Someone mentioned that my 1973 "Federal" Stag possibly would be a Mk 1.5.
What are the differences between that and a Mk 1 or a Mk 2?

[LAMBRETTLAD]

I think there is an explanation in the members area?

In short, it is a Mk1 shell with Mk2 trim. It will have Mk1 doors and locks, but seats, dash, instruments, badges are Mk2. There are a few more differences, but those are the main ones.

You forgot to add there the best ones as well Dave

My mk1.5 has a mk2 body, doors and latches, seats, engine, radiator but mk1 cooling fan and dashboard. It also had a bright front grill and steel wheels when I bought it, but I have added the black paint to the grill and fitted standard alloy wheels.

The differences between the MkI and MkII Stags

On the warning light cluster, there is a temperature warning light which is triggered by a switch on the offside cylinder head. This proved to be so inaccurate that it was discontinued on later models. A factory modification was circulated to British Leyland dealers to cut back the wire from the switch so as to make the light inoperative.

The next change came in early 1972 – the water system was redesigned although the waterways within the engine were left unaltered. Externally, the radiator is now a sealed unit with an expansion tank now running at 20lb instead of 13lb. A ‘U’ hose connects the rear of the thermostat housing to the water pump housing. Previously there was a three way union connecting it to the heater rail. At the same time the air filter box was redesigned and now draws in cold air from above the radiator and hot air from the near side exhaust manifold. A heat sensitive vacuum control flap decides whether to select hot or cold air. At this time a chrome moulding was fitted to the sill panels. When the Mk II model was introduced, the only change in the engine was that the combustion chamber was reshaped and the pistons now have a dome on top. The manual with overdrive was now standard using a ‘J’ type overdrive instead of the ‘A’ type as used in the Mk I car. Tinted windows were now standard along with a laminated windscreen.
The side windows were removed from the soft top and mohair material with a fawn lining was introduced, but not on the early Mk II, ie 1973 production. The background colour of the grille and rear quarter emblems was changed from silvergrey to black. The sill panels were matt black and the rear number plate panel was also matt black. The interior lights were removed from the door pillars to one single light in the centre of the roll-over bar.

The interior trim was slightly redesigned and the front seats now incorporated fittings for head rests. Instruments had chrome lip to bezel, and the fascia was redesigned. A smaller diameter steering wheel was fitted, and twin coachlines were introduced. In 1974 seat belt warning lights and hazard warning lights were introduced. 1975, air conditioning became no longer available, and tufted carpets were fitted. Brushed aluminium sill plates were fitted in 1976 and alloy wheels became standard. The number plate panel went back to the body colour. The handbrake lever grip was redesigned, and a push button reset trip-on speedo was introduced. In 1977 the auto gearbox was changed from the Borg Warner 35 to the Borg Warner 65. Rubber inserts were fitted to the steering wheel spokes.

If it has Mk2 door locks, it's not a 1.5 unless someone has done some major surgery on the B pillars and fitted Mk2 doors. Or it's been re shelled.

The 1.5's are the last of the Mk1 shells but built as a Mk2 Dave so your car is an early full blown Mk2

Technically there was never a designation of Mk1, Mk1.5 or Mk2 .

My car is a 1973 L reg commission number 23136. There is no evidence that it has been re-shelled or had major surgery.

1977 for BW65? Don't think so - look after a 75 with a lower comm number to mine and mine is early Oct 76 and we are both "phase 3" with push button speedo and BW65 from factory (as denoted by an A instead of BW at the end of the comm no).

Mines 25394, built august 73 and is a MK1 shell, Yours should have the early type door locks.

Ian, you are correct, I have just checked my door catches against the rimmer diagrams and I do have mk1 catches. D'oh
