Dimensions of the long frame plow?

[TravelinJavelin 620]

really have been looking to find a snow plow locally or within 200 mile radious for my 953 so might have to have someone build me a frame at least and owners manual doesn't state dimensions also i had asked way back along in another post about differences from the C-series also which never really got answered now i'm assuming the rear hitch brackets are different because i've seen that these will interchange with gt -14 and D series tractors trying get  something together before winter
