Timing chain guides

[CCTGENE]

Would like to replace the timing chain guides as well as the timing chain itself on my son's 89 quad 4. This car has the original double row chain which can be order from any of the local auto stores. However, none of these store list guides for the double row only for the single row. My question - are these second design guide compatable with the double row chain, if not, does anybody know who sell them? Will go to a Pontiac dealership if necessary but only as a last resort!

Thanks
