Side Discharge Grass Catcher ( Universal Fit/Generic?)

[ibuzzard]

I recently bought an NOS 1968 MTD lawnmower, rebranded as a Sentry Hardware mower. Fresh from the box, Sentry Model 020-8, MTD Model 118-020--063. It has never had gas or oil in it.

I would like to purchase a new or excellent used grass catcher for this side discharge mower, and will provide accurate dimensions/description by telephone, if you please!

Thanks for any help, in advance. Steve.
