Out of curiousity, what's the difference between the LT1 and LS1 tranny cross-members?

Also, is there a mounting spot to retain my convertible x-brace? it mounts to the cross member I belive (I'll check this weekend). (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)

Yep... I slid under there this weekend.

The convertible X-brace comes in 2 versions I belive... one for auto's and one for manuals. The manual version uses six (6) Class 9.8 bolts to attach to the chasis. Four of the bolts are the normal ones used for the tunnel-brace, and the front two are bolted to the tranny crossmember.

Of note is that the X-brace actaully has 2 nuts welded to the back side of the X-brace. While the 4 rear bolts pass through the x-brace and thread into nuts welded to the car chasis, the front 2 arms of the X-brace actually slide in above the two bolt holes on the cross-member.

I'd love to drop some weight, save my tranny from damage (in fact I think I may have stripped one bolt in the front torque arm mount), and increase my torsional stiffness... but I don't want to lose my x-brace in the process.

I know that SLP used to make a replacement x-brace that used narrower plate steel and made room for long-tube headers... but I'm happy with my stamped steel version for now.




FYI, not that it matters in this case, but the bolts used as 8mm x 1.25 mm/thread x 20 mm UHL (M8x1.25x20).... I know cause I stripped one while fastening it down this weekend. :\ Getting longer bolts would be useful for those of us with diamond-style SFC's.... my bolts are barely long enough on the 4 rear spots due to the increased thickness of the KBDD SFC's I welded in a few years ago. They still work... but an extra 5mm UHL would be ideal.

They also work in the LS1 front caliper guide pins.

Nice. ARP also makes 5-packs of 12-pt stainless M8x1.25x30mm.

Although the ARP pack is only 5 bolts, and the brace needs 6, I'll need to go bigger on 1 of the bolts anyway... I backed out the stripped bolt today and sure enough... it was the brace's nut that stripped. The threads came out cleanly sheered... the bolt was fine.

I'm starting to hate these thin metric-sized threads (and considering the use of a torque wrench for everything :|).

Ryan,

I wanted to let you know that the relocation bracket arrived on Tuesday. I left it with the shop that's doing the trans work Wednesday morning. Looks like a nicely designed and sturdy piece. Once I get the car working and back on track, I'll let you know what difference, if any, it makes inthe car's performance. However, considering the issues I've already had with the trans, anything that takes any stress off of it is a big improvement in my book.

Dennis
