Hi plumberdave
I too have had to go down this route, I have found a sierra auto with 2 litre pinto so the box will bolt to my block, I intend to have it recon with a manual valve block and gear set from Scorpio cossy box when funds allow, I'm not expecting this to manage lots of power but stg1/2 I'd be happy with, I think my box is the a4ld not sure if its another name for c4 ? Just keep a look out for a Granada/sierra with 2 litre pinto automatic if u find this is the one, the flexplate will need to be modified to fitnto 9 bolt crank, good luck keep me posted
