Chris,
When/if you find a 2.29 rear end and you want to get rid of the 3.73
posi rear, I would be very interested in it. I really don't want a
2.56 geared rearend in my vega. If you decide to get rid of it e-
mail me at vega_guy@ hotmail.com
Charlie
PS: If you can't find a 2.29, just remember that I do have two 2.56
geared rearends one posi, the other is not, both are 5 on 4-3/4 bolt
pattern.
