My dad is looking for 2 modular flat bed Sportrack bike mount things to add to the back of his car (so he can take his 4 bikes instead of only 2 now). It looks similar to the CTA bus bike racks.
They apparently stopped making them when Sportrack was bought out.
If you have 2 or know where he can find 2 please let me know!
If he's willing to check other racks, saris has several that fit in the truck bed or on the trailer hitch. They can handle upto 4 bikes as well so that should do it.
Two important things for him, a) he already has two and would like to just find two more instead of a whole new contraption and b)he likes the flat bed modular style (like the cta buses).
