Fit a 1500 v6 torque converter and a s10 v6 converter, one being the larger pattern the other the smaller. Corrected the spacing for a non-LS small block converter up to the LS platform. Slightly noisy when cranking but works. Great price to complete a junkyard swap on a budget. Quality is with in reason for a street vehicle. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hu/products/554086087-ls-swap-th350-flexplate-adapter-kit-compatible-with-4l60e-700r4](https://www.desertcart.hu/products/554086087-ls-swap-th350-flexplate-adapter-kit-compatible-with-4l60e-700r4) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-08-13*
