A very warm welcome to the forum.
Cheap Sierra's are hard to come by these days, mosk folk are wise and know what they are worth to KIt Car builders !!
Having said that, one will come along when you least expect it & at a price you'll be comfortable paying.
Perhaps TT will let you strip one of his Sierras being as you are local & all that
I too have a Red Top sitting in the corner of the workshop .... It keeps calling to me
Going to stick with the Zetec for the time being, after IVA who knows what'll happen
