Need 2 replacements

A home owner from Fair Lawn, NJ says:
Would like to confirm this as a possible series 351. The metal channel part measures 9/16" (1/2") wide at 13 inches long. The 15-002 shoe and a 19-002 top attached look and measure the similar to the picture description dimensions. The stamp marking is 1210.

Paul from SWISCO responded:
If you have a 19-002 top and 15-002 bottom, then our Series 351 is the correct choice. Just make sure the size of your shoes match the dimensions we show for both of those parts. I cannot tell what size your parts are just by eyeballing them.
A quick learner says:
Upon reading your review and seeing a similar post about the bottom shoe, mine measures 1 1/8". That means I need the 390 series. Thanks and I placed an order.
