help in year identification

[bjr704]

New to the forum and have been impressed in how knowledgeable you guys are on these carts.

I recently received an older cart from my dad but it doesn’t have a serial number tag on it to check years. He says it’s an 89 but the body looks like the 76-87 vintage. The reason I ask is from another post it said that in 89, motors went to the 3pg with horizontal muffler which is how mine is laid out but the body doesn’t match since I thing in 88 they switched to the bumpers , maybe the person he got it from may have done an engine swap or muffler swap? Just looking for some insight for when I need to order parts.

Thanks
