im looking at possible options for a 5 speed box to fit in my leggera over the winter i could go for the type 9 box but they are getting pricey these days and i would have to change/do some chassis mods to get it in there .so i was thinkin mx5 or rx8 i believe these are both rwd boxes but im not sure of size in comparison to the type 9  also the prop could be an issue if they are different splines .any one with experience on this ??? your advice would be appreciated

The 7 1/2" clutch fixing bolts will be on a different radius

You can check it James as you have both clutches

Yes im sure , the 1600 ran a 7.5 inch clutch

i checked today with the supplier of the conversion plate about the clutch plate and it can take the 8.5 inch theres plenty of room for it the guy said . but im thinking if i change it to the smaller clutch i would need to change the flywheel as well ?? can adrian or daryl confirm if my thoughts are correct on this

Yes the Ford fits James but its slightly smaller

yep its just the prop end for the box i have daryl apparently thats the only bit i need im told the ford one fits but you run the risk of damaging the gearbox

Is that RX8  a carbon fibre prop James

hi guys i thought it was the 8.5 as thats what was already in the car , but since it uses the 7.5inch  23 spline that suits me even better as i have a full new clutch in the shed (result ):)  i have the prop shaft that came with the box but will be getting a professional to do that bit . i had thought of the type 9 or mt75 ? but they still require the mods that im going to have to do and both are getting quite expensive looking at £300+ for one that needs work done at the moment im looking at £250 and thats me got all the parts required still have the prop to do but the up side is the rx8 box is comes with a nice smooth shift on the gears and the ratios are fairly decent as well .much better than a 4 speed . im quite lucky  as i have had the offer of a 4 post ramp for a week to get the most of the welding done and hopefully set up the engine and box .

I looked into doing this conversion but I could not make the gain worth the cost with the engine choice available at that time
