86 4-Trax plowing shocks

I just collected a 1986 4 Trax 350, with a plow blade and a Storm Cab (one of the heavier solid-plastic ones). The front shocks are sagging under the weight of the plow. Any recommendations on size and brand of shock to replace the stock ones? PO fortunately replaced the rear ones at some point with something that at least has adjustable pre-load.

I’m sure that I will be having more questions as I dig into my new purchase a little.
