Two ways to buy this kit
Universal — core kit, $1,390. The A/B/C adapter core itself: what physically joins your engine to the transmission. This is the right choice for a resto-mod, a custom chassis, or any build where you are making your own mounts and plumbing.
Complete kit. The same core plus every chassis-specific part for that vehicle — mounts, cooler adapter, lines, shifter and park-release hardware. Everything below is itemised at its normal individual price, so you can see exactly what you are getting and check it against our other listings.

More about this kit
Built for BOP with a left-hand starter
GA7 is the dual-starter-bubble version of our GA3 kit. It exists for BOP engines running a left-hand starter, which the single-bubble GA3 case will not clear. Same Dodge 8HP70 · 75 · 90 · 95 transmission, same contents, same price.
It also fits SBC, BBC and LS with a conventional right-hand starter — but if that is your engine, the GA3-V3 kit is the one built for it, at the same price. Being a BOP engine does not by itself put you here — the starter side is what decides it.
[ ! ] GA7 does not fit Gen 5 LT
Gen 5 LT needs a revised rear main cover and bolt clearance that differs slightly from LS. That revision is in GA3-V3; GA7 is still on V1, which is GA3-V2 plus the left-hand starter bubble, so it does not have it. For a Gen 5 LT, use GA3-V3 (Dodge 8HP) or GA4-V2 (BMW 8HP). There is no left-hand-starter BOP counterpart to GA4 at this time.
[ ! ] Confirm with us before ordering
GA7 is built in small batches. Message us before you order so we can confirm fitment and current lead time for your build.
