Thanks all, good suggestions and info here. The casting numbers are 3756519, the ID stamp is F0929E, the block looks like it has bosses on for side mounts.
Stupid question, what do mean when you say remove the front clip? Radiator and fenders?
I am some what limited in my capability Bartomos so I will have to go to a professional shop to hang this in but want to know what it entails before I go. I don’t have a cherry picker and don’t weld. I have the 283 and it seems a shame not to install it
