That cracked me up.

Some guys really dig the coil over replacement front suspensions. I see them as a really expensive way to reinvent the wheel that rolled just fine.
Some proponents claim that the $4500 AlterKtion gives them great header clearance, then they install the very same TTI headers that fit a stock car with a k member.
You can spend less than $2000 and have a very capable front and rear suspension with OEM 100,000 mile durability.

Regarding the transmission, a 904 is fine if rebuilt properly and if used with less than 350 HP. I'd prefer a 999 though. They look the same externally, but have a lower 1st and 2nd gear for better acceleration out of the gate. From my understanding, ALL 904s built after 1980 were actually the 999 low gear transmissions, so if you are looking for a replacement trans, search for newer cars, trucks or vans.
