What's it worth question

What would be the current value of a Sierra T5 cossie box in good condition these days?

£50 plus postage I'll have it LOL, save me doing a rebuild on mine. On a serious note they can fetch strong money especially if two people want one at the same time. I've seen them fetch up to £700 +

Thanks for that, just seen one on ebay for £1,200, and wondered if it was a realistic price.......

What are the differences or advantages between a T5 and T9? There seems a huge price difference between the two.

The T 5 box is a lot stronger so suitable for very torquey motors ie v6/8 plus turbo applications as its more the torque that kills boxes than revs. The T5 has quite wide ratios so not really suitable for engines with a small power band although there are close ratio kits availiable now. Originally fitted to a lot of yank motors.

Originally fitted to Mustangs, mine was fitted to my NASP Cossie 265 brake with nos well over 300, with no probs, Mk3 full weight Cortina it made 13.1 on the strip.
