I have blower housing and screen off of a B43M Onan engine. It seems to be in very good shape, but I will let the pictures describe to your specs. Please  e-mail questions. Thanks For Looking...... If you live anywhere other than the lower 48 states please contact me before bidding for a shipping quote...Shipping for this product is listed in the shipping info. below, I just guess at how much it cost to ship items, so sometime it does not cost quite as much and sometimes it cost a little more. Either way shipping is the amount listed in the listing, so take that amount in mind when you bid, no more or no less.  Thanks For Understanding.......
