The transmission crossmember isdesigned to raise up into the pocket in thefloor. This provides extra exhaustclearance. The transmission crossmembermay have to be slapped to get it intolocation. A firm slap with the palm of yourhand will usually do the trick. A plastichammer would also work.Tighten the transmission crossmemberbolts before bolting on the frame. If thetransmission crossmember mounting boltsdo not fit centered in their slots, have someone pull the frame apart or, press ittogether while you tighten the bolts. Thiswill make the crossmember easier toremove and reinstall after the frame isbolted to the body. Also, some of the moreswept back crossmembers (like the Turbo400 model) will touch the floor slightly afterthey are installed. If this condition causesa rattle in your car, use a body hammer topush the floor up where it hits thecrossmember.Aligning The FrameThe first step in aligning the front end is toput the alignment pins in both the firewallbody mounts. Do not remove any of theother body bushing bolts. If your front sheetmetal is correctly installed, getting both pinsin will be easy. Do not expect the radiatorcore support 1/2” bolts to be centered in theurethane bushing sleeves. If it appears thatyour core support won’t allow the frame to bepositioned correctly, remove the front bodymount bolts and continue with the alignmentprocedure. Push the driver side alignmentpin against the body mount bracket andtighten the body bushing. Repeat thisprocedure on the passenger side.917703 Page 79

Measure from the lip on the rocker panel tothe side of the frame clip at the front of therocker panel and the rear of the frame.Bump the frame around until the frame isparallel with the rocker panel on each sideand the same distance from the frame tothe rocker lip on each side. If the lip underthe rocker panel is not straight, use a bodyhammer and dolly to straighten it beforemeasuring. Try to bump the frame aroundso that the largest measured differencebetween any two of the four rocker panellips is less than 1/4 inch.After you have finished the previous step,verify the distance from the rear framegauge hole to the back of the frame. Thelength should be within 1/8 of an inch fromside to side.Page 80 917703
