Okay, just to be clear, I can bolt in a stock 929 shock as an improvement on my 5th gen, and all I might need are some washers/spacers to get this correct? There are lots of 900/929/954 shocks out there. Some with white and some with yellow springs. Are they all the same? I like this idea and the inherent low cost of the upgrade. There are lots of decent looking low mileage shocks for sale for less than $50!
