Hi Toby
I have emailed Bara and he gave me a price on a new thick wall cased gripper front diff costing about £2300 inc vat
I am starting to prep the car for sprinting and hill climb regs and they are all standing starts so will be a lot harder on the front diff hence me wanting to update it but as you said and Bara mentioned to me in the email it's the CWP that breaks normally but as I really don't want to change back to 3.6 diffs I don't have much choice it seems
