That's cool, atleast you didn't have an HF tranny where you'd be going through the traps in 2nd gear!
I used to allways have a couple of SI trannies in the shed but they've all been sold or dealt away I believe. A friend of mine used to have a '90 HF with a D16A6 and an HF tranny, that thing would hold 2n'd 'till 90mph it was crazy.
