2008 Back to Back Car Building- Recap

BUMPERS - Any year- all seams of the bumper can be welded but no adding of any metal all brackets must remain stock and in stock position but can be welded solid. wire or chain can go around the bumper but not in front of the radiator for 2008 also 2 flat plates 4x4in max can go from the bumpers to the frame (not the body) to keep the bumpers from coming off.

CORE SUPPORT- It may have a piece of angle 4x4 across the top of the support but can only be 1 inch  longer then the largest radiator. on pre-ran cars the core support can be patched/welded back up to hold the radiator but to much weld and you will have to cut.

BODY BOLTS- Can be changed the bolt size max is 1inch washer max size is 4inch dia.

BODY MOUNTS - The mounts can be changed to a 1 inch stack of washers or a hockey puck type of mount if you decide to use the rubbers you must keep some metal in the mount to get the one inch gap that is required. The front two core support mounts can be altered with weld and all thread , all the other mounts must remain stock as for rust we will let you weld washers into two mounts that need fixed due to rust .We at any time be for any payout may ask you to remove a body mount to make sure there all not welded.

FRAME- Frames can not be pulled down past the stock position in any way. If we fill it has been altered or something is not write weather it has been welded on or just pulled down  you will not get to run and may have to be loaded . In 2008 you can weld the top frame seam from the front of the A-arms forward . You also can shorten the front of the Lincoln . You also can swap frames but it must stay ford to ford and chevy to chevy with all frames being 80 or newer as for rust one spot per frame only. Bad frames can be clipped but only at the cross member ( 90 degree Butt weld only). You can weld up to 6in max of mist frame seams 1in on 1in off =6in max per frame. Pre-ran frames with damage can be repaired with the 4 - 3x3 plates we allow you to use. You can not have any type of hump plate and you can not use HD gussets on cars that don’t come (factory) with them or load, plate or pin the rails,  humps or boxes in any way and if done you would not be invited back.

BODY-All doors, trunk lids, tail gates may be welded with 3 inch max plates 1/4 inch thick. Plates can not over lap or hide other plates. All window frames can be tack welded or wired in the corners of the doors. No thick plates or pipes in windshield wire or something equal to wire (1stock car leaf spring). In the back window wire only (2 spots from roof to speaker tray only). Trunk lids can be sled up under the speaker tray and welded or bolted into place plus every trunk lid must have a 12x12 hole cut in it. Trunk lids can have all thread from the floor pan only thru the center of the trunk straight up and down (2 spots). Tail gates can be removed or cut down and re-welded. You can not cover up any tail light holes they must stay open . For tucking wagons please call there are restrictions.

ENGINE- Any type but must be bolted or welded in on the engine cradle there can not be any plates or pipes coming off the motor to the frame rails. If you do use chain (1 per side) it may only go to the engine cradle or a factory bolt(not welded) in front of A-arm. You can use a distributor protector to protect the distributor only not the sides of the engine the protector must stay on top and bolted on the back side of the motor. NO engine protectors.

REAR-END-Any type of 5 lug Axel rear-end. Rear-end must use the coil springs the control arms can be modified but must be mounted into the stock position .If your putting a old style rear-end under a 2000 and up model be carful on how much welding you do. the only welding you can do is just enough for the 4 rear-end brackets. if we fill the brackets are welded in a way that they make the car stronger you will have to cut.
In 2008 the protectors are for the rear-ends only no tubing plates or chain on it. The protector can not be very wide just a few inches past the tubes. The shocks can be replaced with one inch all thread in that position or inside the coil spring and can go up inside the body and use the all thread for two more body mounts.

CAGE- It may be a 4 point cage with a over head bar (straight across) All bars must be sheet metal to sheet metal. The bar behind the seat can sit no further back where the kick panel meets the bench seat. The front bar has to be at least 6 inches from the center of the fire wall and must go over or under the steering column. The gas tank protector must come off the back bar and only be 2ft. wide. The gas tank can sit on top of the protector or down inside the protector. The protector can go all the way against the back rest metal but can not be welded or bolted  to it. The only two kickers that can come off the cage is the one in center of the front bar going to the dist. protector and the other is the angle bar behind the front seat to keep the bars (square) from getting into the gas tank. There will be no other crazy bars aloud so don’t ask.
(3inch triangle max on gussets for the cage)

GAS TANKS/BATT. BOX, TRANS/OIL COOLERS- In 2008 there will be no gas tank boxes gas tanks will be mounted to the floor board or on top of the floating cage. In small cars no tunnel tanks boat type derby tanks only .All batt, boxes trans and oil coolers can not strengthen the car in any way or will have to be taken out.

DRIVE SHAFT/ TIRES & CHAINS- Any after market shaft O.K. Any ,car, truck, forklift, tractor tire ok.

HEIGHT LIMIT- Built cars must sit level within 5 inches with  NO car sitting lower then 18in.,higher then 23 from the bottom of bumpers.

In 2008 these are the rules so don’t call and ask to do something different. Build what we let you build, and come and have fun. Do not read between the lines or seek out gray areas. If you can’t follow these rules please just keep the car at home. Also no refunds on overbuilt cars or drivers telling me they did not know the rules. Rules will be held to the 1in. driver friendly rule. Any more & you will cut.
