Safety first.....Dont mess with the OEM grate.

im gonna try putting the oem 1300 grate back on

no, no, no

OEM grate is not safe on a modded ski, it allows teh pump to get overstuffed, which can cause the ski to jackknife on you

OK OK OK no 1300 grate but
will someone tell me what solas dynafly to get!

[great lakes gpr 1200]

800 or 1200 grate

You missed this question? If you have a 800 grate you WILL spin out of the hole. if it is a 1200 that's not and issue.
If it is a HO pump you will need a 14/20 DF If it is a 03 pump you will need a 14/20 concord.
