Can anyone check a dimension on some DCOE/DHLA?

Can anyone check the centre to centre distance of the bolts used for holding the trumpets onto 45 DCOE/DHLA carbs please?

AFAIK they share the same centres distance, I am just looking for some short trumpets for my new throttle bodies.

Thanks,
David

Just measured one, 66mm.

Overall 72mm as the vernier measures outside to outside of the studs, less 6mm to get centres.

Excellent, thanks. I need some with 65mm centres, so DCOE/DHLA ones will be close enough

40 DCOE DHLA ADDHE are 65mm centres, I sold a set to ritchunt a while ago and checked them for him.

I still have some 40's and will check for you if you like?

Thats OK thanks, I need 45mm bore trumpets

you can also use IDF style trumpets, only needs 0,5mm of reaming of both holes to line up on DCOE style throttle bodies/carbs

I used IDF's as finding 100mm long ones for DCOE is almost impossible

I have some 100mm long ones.... which would fit

Flak,

I have some 45mm x 50mm trumpets that are surplus to requirements. Pics are in my archive under 50mm ram pipes. They are off my dellorto's and are not perfect but may be of some use?

If they are of any use, make me an offer.
