69 had a 383, don't they have references books/puter they can use for bending pipe for an A-body?? It's not like they have to do it from scratch . . . Rog
well where i work we do have tons of catalogs and bendercards with basicly every american made car you can imagine starting from the 40´s to about year 2000 its all for manual bending with a good old Huth bender, would surprice me if there would be hard to find a place like that in US
small problem i can see is that when bending up pipes in a non stock tubingdiameter is that it sometimes will make it fit real bad and in those cases it would be easier to just custom bend the whole deal but sometimes it works out nicely, and since you want the pipes in 2½" wish is a good pipesize you probably want it mandrelbent also and thats what makes it alitle harder to find localy since normal bendercards for a compresionbender measures everything diferent its just not possible to bend with the same referencecards
if you would like it mandrel bent, but iam sure if you find the right place with the right people they will do it for the right kind of money and make it real good! unfortionaly every one isnt as stupid as me and like challanges outside whats in the catalog or hanging in a rack....
