Door cards? The SS1 type vary by at least a couple of kilos each! Early ones were REALLY dense.

Sabre vs SS1 overall weight I don't think there's much in it, various areas where it's lost and gained on both cars, which sort of levels out, examples.
The Sabre bonnet is much lighter
The Sabre has no rear armature and only the radiator section at the front, with one headlamp motor. The Cobra seats from the Sabre are lighter too I reckon.

What you chaps want is a nice early 1300 SS1. Tin wormed's chassis. few kilos less block and no superflous 5th gear. The air box is made of plastic. Proper boggo spec had no arm rest, headrests or passenger mirror. Raceweight interior trim (minus the red piping)

I'll try and get one on the weigh bridge, reckon it might be closer to 850 than 900...

yeah but whilst its light enough to blow away in a stiff breeze, its not powerful enough to make any headway into said breeze when its running... :lol:

I agree a 1300 in pov spec maybe 820kg-ish with hood, single mirror etc.

oh, so keeping up with an ageing commercial vehicle is your benchmark is it Mr Howard??!!, in that case my sons got a 'pull back n go' toy car that's also more than a match!

I have owned and driven a 1300 4 speed SS1 with galv chassis....zzzzzz zzzzzz zzzzzz, what, who, sorry nodded off at the thought of it!

as for decent 1300 SS1, I assume you mean one fitted with a 1900CVH, zetec or hotted up 1600? :lol:

Nope - one with all of its original cam lobes intact...they certainly rev a lot freer than a 1600 IMHO - that short stroke and lighter crank pays dividends even with the VV carb doing its best to strangle things. Must have been the galv chassis holding your back ;)

I'll wait for b.c. to reply to the commercial comment as I know I'll get nowhere with you...

cam lobes intact, if not the drivers frontal lobe...
revs freely? yep, so does the heater fan but that's fruitless also

awww, bless 'ol BC, he does fly the flag for the relic, but its as a pointless as an Italian army really :lol:

having said all that, id rather have a pov spec 1300 than a commercial, so its all relative I guess :mrgreen:

Some recent weights I measured.

Gearboxes:
Type 3 - 24.0 , matching bell housing 9.2
Type E - 25.3 , bell housing not present
Type 9 - 32.0 , bell housing 11.2

So that's 10kgs Between a 1300 and 1600 to start with!

Door cards:
Type 1 - 3.2
Type 2 - 1.5
Type 3 - 1.6

With the careful selection of certain parts, one could build themselves a rather light road going sprinter.....

Bare body tub is already listed - if my scales are working I could probably do the lot today.

Cheers Jim missed the standard diff at 23.9 so I'll update that & if anybody has a viscous LSD lying around?

The bodywork/tub & bonnet weights I'm after are for the SST. A long shot I know but I'll work backwards if I need to.

The rest off the weights are generic so will help all. Cheers
