I have been thinking of buying a Strange 9 inch centre 3.5 31 spline whilst US$ is low and wanted to see if any of the upgrades offered below would be worth including? I was already going to get the polished chrome moly yoke. Anyones input appreciated....except maybe Bonnevista

PRF170P Strange 9" polished LW aluminum center section- fully assembled with nodular iron posi-unit, aluminum street
support, 3.50-6.50 standard gear set and S-Series yoke.


OPRF07 Upgrade- chrome-moly yoke... $35.51
OPRF09 Upgrade- Tractech 28, 31 or 35-spline (Detroit)
locker or Truetrac... $171ºº
OPRF11 Upgrade- 35-spl. billet Lenco locker... $350ºº
OPRF14 Upgrade- billet half posi-unit... $27.10
OPRF15 Upgrade- Strange NASCAR gear... $125ºº
OPRF35 Upgrade- polished chrome-moly yoke

Well, first of all you need to........oh sorry, you said except bonnevista.:mad:  

I knew you'd be first in......

Curses!!:bats:

I had some really good advice for what you can do with Ford parts!:exact:

Pete i just bought a 28 spline detroit locker 9 inch  centre , i rang peter from sydney mustangs and could you believe it he had a complete 9 inch from a mustang which will fit my car without modification so i snaped it up , its at chris sinclairs now he is going to strip it and send it out to get sand blasted and powder coated , so not long now for my 9 inch diff........................................sharon can't wait

What car is this for?
What sort of HP?

Are you going to see the polished stuff???

Its for a future project with an aluminium housing so no point in cutting corners on the centre.....your only going to see it if you bend over.....not sure what motor but possible late model Ford stating that they are 500hp (but not sure what to believe)
