Looks like you have this sorted, but for info I dug out the following a while back: The connectors are AMP / TE Connectivity MULTILOCK .040 Series (first series, not II or III), Speedo and early tacho - 8-pin part no. 174044-2 RS 362-8768 (£0.94 ea) Later tacho - 20-pin part no. 174047-2 RS 362-8796 (£1.03 ea) Contacts for above - 20-22 AWG part no. 173681-1 RS 712-1889 (£5.10 for 50) Other contacts also availabe to fit this seres. Cheers, Graham.

Thanks Ed - much appreciated... I'd like to take this please, if I may. MM7 - I will message you to sort out the details. Cheers, Graham.

I'll claim next in the queue for this please, if Ed doesn't take it... Many thanks, Graham.

I'd also be interested in a pair of these, please, if you have any left. Many thanks, Graham.

As Jonathan says, AMP Multilock 040 series, part no. 174044-2; RS 362-8768, £1.60ea. You will probably also require contacts, AMP part no. 173681-1 (20 AWG); RS 712-1889, £6.10 for 50. Cheers, Graham.

Still looking! With much appreciated assistance from Wrightpayne, I have now determined that a K-Series top does not fit a Vauxhall belltank! So still looking for a Vauxhall top cover / filler neck.... Graham.

Hi All, Bit of a long shot, but does anybody have a lid / top cover plate / filler neck for a Vauxhall dry sump bellhousing oil tank, that is surplus to requirements? I suspect the K-series one might also fit, as they look to be very similar? Would consider complete (Vauxhall) bellhousing assembly. Cheers, Graham.

Gordon - sorry I wasn't quicker with my post. I only get on the pc sporadically at the moment and had only just read your thread! Anyway, glad you got it sorted. I don't "do spares" as such, just have shelves full of parts from my Vauxhall-engined cars! Good to come across another Sevener in the same part of the world...! Graham.

833VME - Where in Cumbria are you? If you're anywhere near the Whitehaven area I have a couple of the A127 types on the shelf that you're welcome to try. May even be persuaded to part with one.... Graham.

As Jonathan says, standard seat belt bolts are 7/16" UNF, which is 20tpi... Graham.

Thanks for your replies. I hadn't considered that it might be just the increased length that they were after. Of the two I have, the underslung A-frame is 2" longer, at 17" vs. 15", so around 13%, which is not insignificant. Interestingly, as an aside, the longer A-frame is also quite a bit lighter, at less than 1.6kg, whereas the short one is nearly 2kg! I had assumed that the underslung mod was something to do with altering the squat characteristics, which I'm sure it will (just not sure how!), but maybe that wasn't the original intention. I had heard that originally the underslung mounts were further back, so the A-frame length increase would be less, although there doesn't seem to be a specific A-frame available to support this. I had also heard that prior to that there was a bolt-on bracket available, but that it was to convert the standard pivots to underslung, and was used by racers. I agree that it compromises the installation of the lowered floors. Arch box-out the floor to clear the A-frame bush and bolt, leaving a rectangular projection in the outside rear corner of the floor, which may interfere with the seat runner and the old seat mount (crutch strap mount) bracket. The flat floors are also slightly compromised, in that the corner of the floor panel is cut away, therefore the panel is not riveted and sealed to the steel right into the corner. Also, the seat support channel under the floor is cut down to half its width to clear the A-frame bush, losing one of its flanges and one of the two steel rivets holding it to the chassis tube. Regarding race chassis, I was looking on the CC parts website and they list the short "standard" A-frame as "used 1991 to 1996, 2000 Race & updated 2001.5 onwards", so I assumed some race chassis were built without the underslung mounts, but evidently not all. I guess something changed in 2000...? Graham.

Does anybody know what the claimed benefits (if any) were for the underslung A-Frame mounts, introduced, I believe, along with the revised (anti-dive) front wishbone geometry, at the mid-1996 major chassis update, and deleted again at the 2001.5 update? I'm not sure whether all (road) chassis manufactured between these dates were fitted with the underslung mounts, as I haven't seen all that many. I don't think race chassis had them. I would be interested to hear if anyone has first-hand experience of these vs. the "standard" mounts and noticed any significant difference. I suspect that the perceived benefits did not outweigh the disadvantages, as they didn't last for long.... Graham.

Ah, yes, sorry - had to brighten it up a bit to see what was going on.... It does show the high effort pedal as being a good bit longer, probably 8 - 10mm. My pedal is much like the standard one in the last photo, but when compared to the first photo does appear to be a bit longer in the top part. Hard to say, really, and there is a lot of years between them... Still don't like the pushrod alignment on mine though! Graham

Thanks Jonathan. 58.4mm sounds near enough to mine, so I'll assume it's standard. Still too high for the master cylinder though!! Would be handy to know how much longer the high effort pedals are.... Graham

Does anyone know off hand what the lever arm lengths of the high effort pedals are? The pedal on my 2001 chassis looks standard, and I suspect it probably is (it's definitely not the chunky high effort pedal 77198A referenced above), but it doesn't line up well with the master cylinder. The distance from the pedal pivot axis to the master cylinder axis is 2", whereas the lever arm on the pedal, from pivot to clevis pin is 2 3/8". The clutch pedal is 2", but is a cable pedal. Both pedals are 7 1/2" from pivot to pad. The original owner overcame the alignment issue using a cut-price version of the CC wedge shim - leant on the master cylinder to bend the pedal box until the pushrod lined up with the hole in the pedal!!
