I think the knowledge and support that comes with one of your TCs would be worth the extra cashI’m based in Leyland, Lancashire (http://www.fullfatrr.com/forum/topic38676.html). I source my torque converters from JPAT near Bristol so it would probably be cheaper for you to buy one directly from them as I obviously have to add a ‘handling fee’ to make it worth my while. Just to give you an idea though, a re-manufactured unit is £230 and a brand new unit £550. Prices are exchange (i.e. you have to supply your old TC) and include VAT but not postage.
