Possible to fit 90 brakes onto series 2a

i want to fit 90 disc brakes servo etc into my series 2A will the front discs fit the front hubs and will the servo fit onto the bulkhead?

Thanks

unfortunately its not that easy! the discs wont fit the hubs, but the servo and pedal box will fit you just have to extend the hole for the pedal in the bulkhead.
You can buy disc conversions for series but they are expensive. cheapest way is to fit range rover axles. bit of hard work with a grinder and a welder but you then get cv joints and discs all round, which is nice!!
