I now have the dimensions for some products in a new table, products_extra_stuff

For example

Code:
> select * from products_extra_stuff limit 5;
+-------------+-----------------+-----------------+----------------+
| products_id | products_length | products_height | products_width |
+-------------+-----------------+-----------------+----------------+
|          18 |             8.5 |               1 |            5.5 |
|          19 |               9 |               1 |              6 |
|          20 |               9 |               1 |              6 |
|          21 |               9 |             1.5 |            5.5 |
|          22 |             9.5 |               1 |            5.5 |
+-------------+-----------------+-----------------+----------------+
If the row for a particular product_id exists is there a way to pass the dims to the USPS module ?

Thanks
