G/box: 140 4 speed/OD M45: Volvo M40 to M41 Conversion.

[Kelly126]

Good afternoon all!
Im planning to convert my M40 gearbox to M41 in my volvo 144.
I have all the parts planned but i just wanted to know how much i need to shorten the propshaft by?
I cant find any numbers anywhere and i would like to get a quote on the shaft shortening before i pull the trigger on the other parts.
If any of you have a shorter driveshaft that would be amazing too, happy to buy it off you
Many thanks,
Alex

Hi I did this quite a few years ago but I had a complete donor there are a couple of places that do driveshafts but depends on your location.

Hi Alex,
Is your plan to fit "D" or "J" type overdrive to the M41.
I have a 122S with D type and can measure the prop front section if it helps.
I am not sure though if a 122 and 144 share the same prop.
