Overdrive Conversion


After deciding to fit an overdrive gearbox to my spitfire, I set about collecting the parts.
I bought the prop shaft, speedo cable and overdrive mount all new from my preferred supplier, T.D.Fitchett and an overdrive mounting plate off Ebay and a fully re-con J type overdrive gearbox from Canley Classics.

The gearbox was collected from Canley Classics and I installed the whole thing over a weekend. The clutch was changed at the same time.
This overdrive conversion, although ultimately quite pricey, has transformed the car and made it a lot more useable.

This it a list of the parts and prices involved:

Fully reconditioned J type overdrive and gearbox Canley Classics £512.87

Overdrive propshaft T.D. Fitchetts £69.00

Overdrive mounting plate Ebay £10.00

Overdrive mount T.D. Fitchetts £14.50

Overdrive speedo cable T.D. Fitchetts £8.50

HP90 gear oil Halfords £14.00




TOTAL COST = 628.87
