This is for 6” dropped I beam hot rod axle master builder kit. Build it your way. Comes with one solid axle and one drilled axle. The suspension components. As well as both disc brake set up and Buick finned brake drums. Truly a build it your way hot rodder's kit!! This is resin 3d printed. These items may need some clean up work as is typical with resin 3D printed part. Some items may ship on supports to minimize shipping damage or loss of parts. Always soak parts in very warm water for about ten minutes to soften the supports. Then gently use pressure from your thumb or finger to remove parts from the sprues. NEVER cut from sprues while dry and cool as it will lead to cracking or splitting damage. If you try to cut a part, do so slowly and gently. Brute force will also likewise lead to damage. I can not be held responsible for your neglect or from damage cause by natural light. I highly recommend cleaning parts in a quality degreaser or isopropyl alcohol before use. I always recommend storing in a cool dark location. Or sealing with a quality clear or primer to block the suns UV light. Please note the UV light other wise will continue to cure the part making it more brittle and possibly causing it to warp. If item warps. Soak in very warm water for several minutes. Then lay flat and allow to dry completely. I use standard Loctite for gluing parts together. You may also use other super glue or epoxy or CA glues. As always. Look at my other items for more great parts. Larger bodies will need to be printed in several parts. It will be your responsibility to sand and glue together. Please note the small scale suspension kits etc. will have fine details as these are  or are very close to true to scale. The builder will need to take care is removal, cleaning and building of these as they will be on the frail side. Likewise master builder kits are just that. They are not for the novice builder, but for a more advanced builder. They too will have fines details. Especially lots of bolt heads etc. If you wish to combine shipping. Please put all items into your cart. Then request a shipping total. Also if you have any questions. Feel free to contact me and ask away! Thank you for your continued support! Jo.
