are 70 b-body bumpers not reproduced? I can't seem to find any on ebay.

tricity bumpers ? got mine from them (70 road runner)

do they do rechromed originals? Probably very pricey?

I need a new rear bumper for my 70' bee, its a little bashed up. (so sending it out for rechrome isnt an option)

But I can't find anybody that does a repro???

they will take your bumper as a core and send you a newly rechromed one. i believe if yours is to bad they might not except it though. a little pricey but not many other options,unless you can find one in a little better shape then yours to exchange. got mine a few years back and it was i believe 300.00 plus usable core. good luck
