My 73 bus doesn't have a front belly pan. Were they fitted to all buses and if so do they serve a useful purpose?
yes they were fitted to all but a lot of people leave them off thinking they wont trap water and corode the floor underneath etc. They are there to protect the underside. Easy enough to replace think you can even get new ones these days. I personally would keep it just waxoyl underneath.
I bought a fibreglass one from nomorerustybits - http://www.nomorerustybits.com/index_files/Page1136.htm Its just a bit too white.
There's one on eBay at http://www.ebay.co.uk/itm/Genuine-g...ervan_Caravan_Accessories&hash=item4ac3fdb31b
When mine were took off it was in really good nick underside ,unlike the rest of the van ,just waxoil it now yearly
